KeyFlips

Shows estimated FBA profit and ROI on every row of the Keepa deals table, and flags steady-selling underpriced books.

KeyFlips turns the Keepa Deals page into a buy list. Every row gets a badge showing what the deal is actually worth to you, after Amazon fees, so you can stop opening tabs and doing math. WHAT YOU SEE ON EVERY ROW • Profit and ROI after referral, closing, FBA (or your FBM shipping), prep and sales tax • Max buy price: the most you can pay and still hit your profit and ROI targets • Sales per month, based on sales-rank drops • Gating: ✅ you can sell it, 🔒 approval required (one click to request), ⛔ restricted • ⚠ AMZ when Amazon itself is on the listing • Green / yellow / red so you can scan a page in seconds ★ GEM FINDER Flags steady sellers with few used offers that are listed far below their normal used price. These are the underpriced books worth jumping on. BUILT FOR HOW YOU SELL • FBA or FBM mode • Your own minimum profit and ROI targets • Use real FBA and referral fees from your Keepa API key, or set your own • Dim rows that miss your targets, are gated, or have Amazon selling • Works with books, music, DVDs and video games WHAT YOU NEED • A Keepa account with access to the Deals page • Optional: a Keepa API key for exact fees, sales counts and the GEM finder • Optional: be logged in to Amazon Seller Central for the gating check (it uses your own account, so results match what you can actually sell) PRICING 7-day free trial, then monthly or a one-time lifetime license, both through Gumroad. After purchase, paste your license key into the KeyFlips popup. PRIVACY Your Keepa API key and settings are stored only in your browser. KeyFlips does not collect, sell or share your data. Gating checks go directly from your browser to Seller Central. KeyFlips is an independent tool and is not affiliated with, endorsed by or sponsored by Keepa GmbH or Amazon.
