Stop guessing. Start flipping.
Know exactly what every Pokémon card is worth — and what you'll actually pocket after eBay fees and shipping — before you spend a dollar. Built for sellers, not collectors.
No credit card required · Free to start
You know the feeling.
You buy a card at a show, get home, list it on eBay — and realize after fees and shipping you barely broke even. Or worse, you passed on a card that would have made you $40.
Fendle fixes that.
Everything a flipper needs
Every feature is built around one question: is this card worth buying?
Deal Finder
Scans thousands of cards and ranks the best eBay flip opportunities by profit, ROI, and liquidity. With a BIN premium adjustment so you're comparing apples to apples.
Profit Calculator
Enter any buy price. Instantly see your net profit after eBay's final value fee, payment processing, and shipping. No spreadsheet required.
Price History
30-day price charts on every card so you can see if a card is at a high, a low, or in the middle of a trend before you commit.
Biggest Movers
See which cards moved the most in price today across the entire market — not just your watchlist. Spot momentum before the crowd does.
Price Alerts
Set a target price on any card. The moment the market hits it, you get an email — so you can act fast while others are still refreshing TCGPlayer.
Flip History
Log every flip with real fees. Track your P&L, win rate, ROI, and best-performing sets over time. Export for taxes in one click.
Calculate your eBay profit on any listing
Drop the extension on any eBay or TCGPlayer page and see the net you'd pocket — free, no account needed.
How it works
Three steps from opening the app to knowing exactly what to do with a card.
Search any card
Search by name, set, or number. Card detail loads instantly with TCGPlayer market price, low price, and eBay 7-day sold average.
See your exact profit
The profit calculator shows your net after eBay's full fee stack — final value fee, payment processing, and shipping. Real numbers, not estimates.
Buy smart, sell at the right time
Watch price history to time your sell. Set an alert for your target price. Log the flip. Fendle tracks your record over time.
Why we built Fendle
I've been flipping Pokémon cards for years, and I got tired of doing fee math in spreadsheets every time I picked up a binder at a card show. I'd miss flips because I couldn't price a card fast enough, or I'd buy something thinking it was a deal and realize at checkout that shipping ate the margin. Fendle is the tool I wished existed — real prices, real fees, real profit, in one place. If you sell cards, I think you'll love it too.
