How it works

How BFF reads a listing

I built BFF to do the boring part for you. Here is the whole thing in four steps, and I followed one real broken listing the whole way through so you can see exactly how it works.

Step 1

First, I scan the broken listings

BFF pulls all the for parts and not working listings off eBay and drops them in one feed. No more digging through junk searches. The ones actually worth a look are right there in front of you.

Live broken listings
  • 2023 Apple MacBook Pro 14" - Apple M3 Chip - 8gb 512gb - LCD Damage$370
  • Broken DJI Matrice 30T Thermal Enterprise Drone M30T RTK Account Bound FOR PARTS$4,000
  • Breville The Oracle RM-BES980XL Espresso Machine - POWERS ON / HEATS *Incomplete$400
Step 2

Then you see the real margin

Every listing shows you the spread, what it costs broken versus what the working ones are going for. That working price is an estimate from what is listed right now, not sold data, so take it as a solid ballpark and not a promise.

Step 3

I price the repair for you

The margin is only half of it. If the seller says what is wrong, I price that exact fix, show you the spread left after you fix it, and link you straight to the part you need on eBay or Amazon.

Step 4

Then you flip it

Buy the ones where the numbers work, do the repair, and sell it working. The gap between what you paid broken and what it sells for fixed is your money. That is the whole game.
