FAQ
How does the Flip List work?
Every day our pipeline compares TCGPlayer buy prices to eBay sold prices (via PriceCharting data) for 50,000+ cards. We calculate the total cost including TCGPlayer shipping, sales tax, eBay FVF, promoted listing fees, and the $0.30 fixed fee. Cards with real profit after ALL fees make the list.
How accurate is the profit calculation?
Our fee model is ported from a live eBay arbitrage system that processes real transactions. We account for eBay's 13.25% FVF, ~2% promoted listing attribution, the $0.30 fixed fee on cards under $10.01, TCGPlayer shipping ($1.31 under $5), and ~10% sales tax.
Which games are supported?
Pokemon, Magic: The Gathering, Yu-Gi-Oh!, Disney Lorcana, One Piece Card Game, and Pokemon Japan. All games are included in both plans.
What happens if I cancel?
You keep access until the end of your billing period. After that, your data is preserved but you return to free tier limits.
What is the Grade for Profit calculator?
We compare raw card prices to PSA graded prices (7, 8, 9, 10) to calculate the expected value of grading. Using grade probability distributions, we show your expected profit, ROI, and break-even grade — so you know which cards are worth the $30 PSA submission fee.
