Tell it what you’re hunting
A search like “151 elite trainer box”, the area you buy in, and the most you’ll pay.

Stop refreshing Marketplace. We’ll sift it.
FlipSift watches Facebook Marketplace, OfferUp, Craigslist and eBay for what you flip, throws out the $1 “make me an offer” bait, and tells you when something lands under your price.
One email when we open. No spam, no sharing — see our Privacy Policy.

How it works
Set it once. It keeps looking.
You tell it what you hunt. It does the refreshing, around the clock.
The noise gets thrown out
$1 placeholder prices and listings over your max never reach you. What’s left is what you could actually buy.
You hear about it fast
By email or a Discord ping, and on a dashboard where you save or dismiss every find.
1 in 4 cheap listings we checked was bait.
Card sellers list sealed product at $1 to fish for offers. When we checked 271 live Pokémon listings around Seattle in September 2026, placeholder prices like that were 28% of what a search capped at $90 returned.
FlipSift filters them out by default.
What lands in your inbox
Just the ones worth a look.
