Is Compz just a weekly list?
No. The list helps you find opportunities. The Grading Desk helps you track the grading decision afterward — from wishlist to owned raw, PSA submission, returned grade, and eventual sale.
Is this a full collection tracker?
No. Compz is built for grading candidates and ROI decisions, not cataloging every card you own.
What do I get for $19/mo?
Full access to the grading opportunity list plus Grading Desk, including up to 100 tracked grading decisions.
Is this just eBay sold listings in a spreadsheet?
No. The fee math is the easy part — we do it properly (correct PSA tier, eBay's cut, time cost), but the real work is the judgment layer on top: PSA 9 floor protection, gem difficulty, and trap detection on cards whose spread looks better than it is. That's the part a spreadsheet can't tell you.
What if the card doesn't PSA 10?
That's the question Compz is built around. Every card is scored on its PSA 9 floor — what you actually net if it doesn't gem — and its gem difficulty, read from how far apart the PSA 9 and PSA 10 markets trade. Floor-protected cards are profitable even at a 9. Cards that need the gem to work get flagged as high-variance or traps, not recommended.
How is this different from doing the research myself?
It isn't — we scan over 1 million cards each week and refresh daily pricing on the top opportunities so you don't have to. Even at 30 seconds per card, manually covering what we do would take thousands of hours. One avoided bad submission covers 3+ months of Compz.
What grading costs does Compz assume?
PSA tiered pricing based on each card's PSA 10 market value. We also apply an 8% annual opportunity cost for capital tied up during turnaround — because slower tiers have a real cost.
What's covered?
Basketball, baseball, football, and Pokémon. More sets and sports added regularly.
Can I cancel anytime?
Yes. Cancel from your account page, no questions asked, no waiting period.
