I built Flipr because I was flipping electronics from Facebook Marketplace to eBay, and the process was just... clunky. Every time I saw a potential deal, I had to manually search sold listings on eBay, estimate shipping and fees, run margin math in my head, and guess what my offer should be. I missed a lot of deals just moving too slow. Flipr simplifies that entire process. It’s a lightweight Chrome extension that opens a pre-filled eBay sold search, then helps you calculate the right offer price based on your shipping cost, target margin, and product category. You get a clean fee breakdown and a smart max offer suggestion, right when you need it! What makes it different? It’s focused, fast, and built specifically for resellers who source from Facebook Marketplace. No bloated dashboards. No SaaS signup wall. Just a practical tool that lives where you work. What I’m most proud of: this was a scratch-my-own-itch build that’s already saving me time and helping me flip smarter. Excited to see what others think and how I can improve it with your feedback!

💡 One of the reasons I built Flipr is because of situations like this 👇

This week I sold an item on eBay for $965.

After eBay fees ($99), shipping ($16), and other costs, my actual payout was $848.77.

That’s over $116 less than the “sale price” I thought I was pocketing.

This is the trap a lot of resellers run into: what looks like a great deal on Facebook Marketplace can actually net negative profit once you factor in fees and shipping.

👉 Flipr solves that by showing you the true max offer you can make up front, with all those costs built in. That way you never overpay, and you only chase deals that are worth your time.

Curious—how many of you have been surprised by how much lower your actual eBay payout is compared to the sale price?
