How I Made 190% Profit In One Year Buying/Selling On COMC

**This site contains affiliate links for which I may be compensated**

On June 3, 2015 I started this COMC account with $100 cash. I wanted to see how much money someone could make over a year selling cards casually on COMC. I came into this challenge already with years of selling on COMC under my belt – so my only purpose for this account was to flip cards already on the site. What most novice COMC sellers don’t realize – sending cards into COMC (and paying processing fees) is the worst way to utilize the website & generate profits.

First, let’s start off with a look at the account at the present moment (7/26/2016). Currently I’m very low on cash – simply because I’ve found over the years pre-National (NSCC) you can normally find lots of people trying to liquidate inventory of older cards in an effort to free up cash for one of the biggest events of the year. Just a few weeks ago, I had over $70 cash – so I’ve done a ton of buying over the last 30 – 60 days. Consequently in a few months – you’ll have the biggest e-commerce shopping day of the year (Black Friday/Monday) … so smart sellers I know are gobbling up inventory now so they can be ready for the big day.

COMC Account Updates

One note about my asking price ($1,165.45) above. It’s fairly well-known by veteran COMC sellers that I would be able to liquidate this account (in a Port-Sale) for about 80% – 90% off my asking price. That would be the turn-and-burn type price. Realistically I think I can get about $0.25 – $0.35 per card … which would value the account in the $250 range. Remember, I started this account 13 months ago with $100 and I could (likely) easily liquidate it for around $250. Of course, I’m in no rush to liquidate this account – in fact, I’m raising prices & driving margin/profit even higher than when I started in 2015! How many eBay/Amazon sellers you know are able to do that??

Let’s take a look at the account stats on a more detailed level – since above only tells a partial story. I get the Total Cost figures below from my sales history, which I have linked below if you want to take a look at all my sales.

Overall Stats:

Cards Purchased: 4,336
Cards Sold: 3,344

Total Sales: $837.53
Total Cost: $546.88

Total Profit: $290.65

2015 Stats:

Total Sales: $344.66
Total Cost: $229.66

2015 Profit: $115.00

Keep in mind this is for 6 months of selling during 2015.

2016 Stats:

Total Sales: $492.87
Total Cost: $317.22

2015 Profit (YTD): $175.65

Sales History Data

Here’s a Google Doc with every card I bought & sold on COMC inside this account. How many eBay sellers you know show their data like this?? The data shows how much I paid for each card – and how much it was sold for.

A few things about the numbers you see above. The 2015 Stats are only for 6 months of the year since the account was opened in June of 2015. Consequently, the 2016 stats are essentially a 7 month figure since they are YTD. Overall the two figures give you about what you could expect over the course of about 1 year.

How Do I Find The Cards To Buy

Almost all of the cards I purchased were via sellers who were running a sale. About 1 – 2 times daily, I visit the COMC recently posted sales list. The sellers closer to the top will have just had their sales posted – and theoretically have not been picked through as much as sales that have been running for some time. I try to focus on sellers I don’t recognize running sales 65%+ or more. On COMC if you go to the recently posted sales – you will find that many sellers are almost consistently running sales. I personally don’t want to spend more than 5 – 10mins per day searching for cards – so I usually ignore any sellers who constantly run sales.

More recently, I’ve been trying to buy cards that are serial numbered to 100 or less. I feel that buying these cards limits my downside a bit because the sheer number of cards available to send into COMC (and for sale on other sites) will be lower than non-serial numbered cards. I’ve also found that you can re-price these cards for 300%+ and they will still sell often enough to make it worth the patients needed. Additionally, when I ran spring-cleaning/Black Friday sales on COMC – I’m able to be more aggresive with my discounts (usually 60% off) which looks good to the customer – and I’m still clearing a very good profit.

Those two buying tips alone are enough to generate a profit on COMC. However, there’s lots of other factors involved in making money. Some of you might have more time and knowledge than myself about these things and could experience higher returns than what I’ve presented. My last buying tip is to buy when everyone else is selling.

Other foods for thoughts. I’ve gotten a lot of feedback about COMC over the last year – many sellers trying to use COMC exactly how they use eBay. Most are trying to send in lots of new(er) cards into COMC – That’s an amateur mistake. Remember, COMC & eBay are two completely different e-commerce platforms. I just showed you can make 190% on an account with only $100 in it … why on earth would you want to send cards into COMC when you can make 190% annualized just flipping the cards already on the site? 

We call this logic: jumping over dollars to pick up pennies in the finance world.

Other than that, in my opinion, selling large volume on eBay is a job I don’t want – one that requires you to invest time into packing/shipping/listing items on a regular basis. Not to mention the customer service you have to provide each customer during/after the sales process. Given all the extra work required to sell on eBay – your margins are going to be (at best) low single digits. COMC has a different fee structure, (that many amateur sellers complain about), but what they are forgetting is that you can run higher margins due to the fact you’re not working as hard for the sales on COMC.

The other point I’ve made to eBay sellers in the past is to use COMC as a way to expand your sales. Instead, so many sellers just want to sell the exact same way they have for years on eBay. That’s a huge mistake. If you already have good sales on eBay – why would you want to cannibalize those sales with the same one’s on COMC?? That’s a business logic that you learn almost day one at any business school worth paying for …. but it’s a mistake I see all too often in the e-commerce world. COMC is a completely different e-commerce site than eBay. Just because the same product is being sold on both sites – doesn’t mean the same type of selling techniques will work on both sites.

Other things to keep in mind. I’ve discussed this $100 account numerous times on the Sports Card Show Podcast – so a portion of the collecting community knows it’s an account strictly to make money. It’s possible my sales are better if I don’t openly advertise this is an account strictly to make money. Also, during 2015 I was focused on rapidly turning over my money – so high margins weren’t something I was concerned about. During 2016 – I have shifted my focus primarily on cards that I can re-price at 100% – 300%+ markup. The only thing to keep in mind is it’s harder to find these types of cards to purchase, and these sales take longer to materialize. Patience is key.

Feel free to share your experiences with COMC below.

About the author 


  • Great article I’m reading years later and now watching your YouTube videos.
    So would you buy any cards? I see post on Craigslist selling boxes of over 10k baseball cards but if they’re all just worth pennies wouldn’t that be a waste of time trying to flip?

  • I doubt this comment will ever get seen and/or reply, but I’ll take a chance.

    I was wondering, if you think it can be possible to start an account with $30 and be successful at flipping. Does the cards moves fast? I am asking because I’d like to start an account so I can grow my PC a bit more. I am collecting mainly Aaron Nola a few other Phillies and I’d like my collection to get bigger a bit, so, flipping might be the way but I am completely clueless about it and wondering if it’s still possible, in 2018.

    • I still think it’s possible with $30, you’d just have to be patient to ramp up to a lot of sales. If you focused only on hot/in season players, you could probably turn your inventory over faster than if you were buying just generic type players. Buying right before the season is a good idea. I was buying baseball in December/January and most of what I bought is more valuable. Just realize $30 isn’t much so you’d be lucky to earn $3/month unless you got lucky.

  • Thanks for all the entertainment and information. I got on COMC after listening to one of your podcasts and have assembled a modest port so far. Even sold a few cards for profit. My biggest question is: how are you locating cards under $.30? That’s the minimum price I can find. I often here you referred to cards bought for $.10 – .15 and I can’t seem to find those. Any help would be much appreciated. Keep up the great work.

    • Here is a video I did where I explain some flipping techniques and what in your settings you need to change to get the .25 off per card: https://youtu.be/e_MXIjvD0Fk?t=4m58s

      You are getting the .25 you are currently spending back when you sell a card, but you might as well not have to pay that .25 so that you can buy more cards to flip. If you choose to ship a card to yourself, you will be charged .25 per card, because that is what this fee covers.

  • where are the COMC buy/sell and storage fees in your calculations? Your spreadsheet looks like buy and sell prices with the fees deleted because I can’t find a card on the site for 12 cents (lowest I found in a quick browse was 33 cents which should be the card price plus COMC fees tacked on to each card).

    • There is an option to purchase cards without S&H Fee’s called “Advanced Re-selling Mode”, you would have to pay the S&H if you shipped those cards, As for storage fee’s there are different levels of fee’s applied each month, however every card listed under 75 cents is free from those fee’s.

    • I might have realized a few of the $0.01/card processing fee on a few cards. I can imagine the total was less than $5 for the entire year because of the turnover. Only in the last few months have I focused on higher dollar cards, simply because I’m getting lazier and other sellers are doing the low-end strategy I used for years. However, even with $50 or $100 in storage fees, this account illustrates you could still be wildly successful considering it only started with $100 and I probably spent more effort writing this article than actually selling the cards.

      Besides, the way I think about is – out here in California – I’d pay well in excess of that to store this many cards. I just bought a house and it costs $37/sq foot. I used to work in insurance, so I know what it’d cost just to insure a small collection. I can’t afford to collect cards and have them at home. Those are things I think about to rationalize the expenses.

      Also – turn on advanced reselling mode. You’re wasting $0.25/card if you’re just reselling it. Let me know if you have other questions.

  • How did you keep track of your total cost? Did you use a spreadsheet? I know COMC has an option to download your purchase history, but it doesn’t show any totals.

    • Wally, thanks for the comment. Yes – these were all cards I purchased on the site. There might be a few ePack cards that register as $0 cost, but I got them by free packs/trading. You can download your sales history and it shows how much you paid and how much you sold it for. It might not be 100% exact, but the gains are so obvious that accounting for every last cost (like eBay sellers do) isn’t necessary. Hope that helps.

  • I began submitting cards this year and have had a steady 55% return on those (post fees). A good ROI can be done depending on the type of cards submitted

    • What types of cards are you submitting? If you don’t mind sharing – how are you sourcing the cards you buy to send into COMC? If I had a good source of cards very cheap – I’d love to submit more cards. Some of what I wrote above were strategies before the cross-listing on eBay. Now I think higher dollar stuff, maybe graded stuff, will move faster than before. In those cases paying the processing fees would probably make a lot of sense. Let me know what you think.

      • I struck a deal with a fellow collector who’s selling me items in bulk. We’ve only recently started (and it was before the cross-list announcement) so I’m planning to scale up on that strategy based on the recent eBay development. I’m banking on the increased exposure

        • Very cool, that makes a lot of sense. I remember many years ago working at card stores and the cash price for cards is totally different than the eBay/online price. I wish I could have that kind of lead source on cards these days. While not everyday, you’d see binders of Michael Jordan or vintage baseball cards with sellers willing to take < $0.10/card. Other times it was a guy with a box of jersey/auto cards - and all he wanted was $0.50 - $1 each - or some trade for the new packs on the market. I think if I had more time, I'd place ads in newspapers or Yellow pages in my area saying I was buying. There's a large segment of people with cards that have no interest ever selling on eBay or online. Our phone would ring off the hook of people who wanted to sell - especially in 2008. Now a localized online ad could probably be more cost effective than Yellow Pages. I wish you well and I think the addition of eBay should allow you to turn over your inventory faster.
