I Don't Think There is Any Way These $150 in CollX Sales Happen on eBay...

CollX has been a surprising game-changer for moving low to mid-tier cards that would likely sit idle on eBay. Here’s how these sales added up—and why I’m doubling down on the platform.

About a week and a half ago I detailed how I planned to sell the many cards I have sitting around my house, collecting dust.

One option was using the bulk upload tool BuySportsCards.com (which doesn’t require scans) and the other was CollX (a strong option made stronger with Card Dealer Pro and an autofeed scanner).

Take a look at that post if you haven’t already:

Well, fast forward, and I’ve paused my sales on BSC.

I still think there is plenty of opportunity with BSC, but I had more early success with CollX, and felt I could go even bigger by going all-in and focusing my efforts on one platform.

Since then, I’ve made about $390 sales on CollX—not a bad start! There is a 10% fee on each sale, which is less than eBay.

Now, some of these sales were bigger cards that would have sold easily anywhere (graded Kobe rookies):

But most of the sales I just don’t think I would have made on eBay, and that’s exciting. This is what I mean.

So far I’ve had 4 sales 10 or more cards in total:

eBay vs. CollX: Why Some Sales Just Don’t Happen on eBay

There’s no denying that eBay is a powerhouse for higher-value cards and rare finds, but when it comes to moving lower-value lots or mid-tier singles, it can be a different story.

Those $10-$30 bundles that sold on CollX? They likely would have sat unsold for months on eBay, buried under thousands of similar listings.

That’s where CollX shines, in my opinion. The platform makes it easy for buyers to snag multiple cards in one shot, thanks to its interface and the ability to build packages.

The $31 lot with Jalen Harris, Willson Contreras, and Taylor Jones is a perfect example—individually, those cards might have struggled to sell on eBay, but as something a buyer could package together, they moved quickly on CollX.

It’s a prime case of CollX creating a more efficient marketplace for sellers looking to move volume without slashing prices or paying higher fees.

CollX Selling Tips

I’m still a rookie seller on CollX, but I think these things help (I also know some of you have been selling on CollX for longer than I have, so feel free to chime in!).

1. Keep Your Images Consistent

Yes, clear scans of your cards are crucial, but maintaining a consistent style across all your listings can make a big difference. When buyers can easily scan through your inventory and know what to expect visually, it keeps them browsing longer.

2. Offer Discounts—Even Small Ones

A little incentive can go a long way. Personally, I love when sellers offer discounts on purchases under $50. It’s an easy way to encourage multiple purchases without slashing prices across the board. Right now, I’m running 10% off anything over $30, and it’s been a nice nudge for buyers to fill up their cart.

3. Set a Minimum Purchase—But Be Strategic

Setting a minimum purchase amount can work in your favor. I list a lot of cards at $0.25, but by setting a $3.50 minimum, it encourages buyers to keep looking. They might grab a few cheap cards to hit the minimum, but they also might notice something higher-priced that catches their eye. Done right, it’s a win-win.

4. Avoid Clogging Your Inventory with Junk Commons

Again, another one that requires balance. Sure, those $0.10 commons might seem like easy sales, but they can clutter your listings and make it harder for buyers to find the good stuff.

Focus on quality over quantity—a well-curated selection keeps your shop looking sharp and encourages buyers to take a closer look at your higher-value cards. Again, I’m saying this as someone listing $.25 cards, but I try to focus on stars, inserts, and parallels.

5. Be Lenient on Offers—Within Reason

I don’t think I’ve countered an offer. I might have rejected a couple that were way off, but I’m lenient.

Don’t be afraid to accept a slightly lower offer. It’s not always about getting top dollar on every sale; sometimes, moving inventory quickly and building good buyer relationships can pay off more in the long run. Plus, a completed sale today is better than a card collecting dust tomorrow.

CollX is transforming into a powerhouse platform by the day. Whether it’s low-end lots, mid-tier singles, or discounted bundles, the app makes it easy for buyers to grab multiple cards in one shot – and for sellers to keep the cash flowing.

I’m still experimenting, but so far, the results speak for themselves.

And hey…

if you’re a paid subscriber here on Substack and spot something you like in my CollX listings, let me know. I’ve been known to get a little crazy for my people, whether that’s major discounts, free cards, or other surprises. I only have about 500 cards listed right now, but there’s plenty more to come.

Sell on!
