06
Discover what you never searched for.
The community deal feed surfaces trending drops across thousands of shoppers. Half the deals you'll take were products you weren't tracking.
02 · the moat
Price data wants to be shared.
Every price tracker before PriceSentry shared the same quiet flaw: you only saw what you bothered to track. Your chart was as short as your memory.
We flipped it. Every user contributes anonymous price points. Every user gets the benefit of the whole dataset. The more people use PriceSentry, the richer the chart for everyone, and the more deals surface — deals you never thought to search for.
It's the oldest idea in data — n makes the network — applied to a problem the incumbents can't fix, because their business models depend on you being alone.

Forever. No tier. No asterisk. No "freemium."
The product is the community. Every new user makes the chart deeper, the alerts smarter, the feed richer. Charging would actively damage the thing that makes PriceSentry work.
Every shopper, your deal scout.
