There's no shortage of ways to find the lowest price. They're all much the same information, and whoever hands it out usually has a reason to send you to one shelf rather than another.
What none of them do is help you understand your own shopping. Which products you actually buy. Which brands you keep coming back to. What a thing costs you over a year, and whether the price you just paid is normal — for you, not for the flyer.
That's the whole idea.
CartEncore remembers what you buy, where, and when — and builds that into a memory your household can actually use. What the kids will eat and what they won't. Which store had that bread everyone liked. The parmesan worth buying again, the ham nobody touches. The small, ordinary knowledge that's impossible to hold in your head but adds up to how a home really runs.
And there's a quiet reason to build it this way. The big chains spend a lot of effort making the normal price hard to remember — moving numbers around until you lose the thread. A record of your own purchases gives that thread back to you. Not to help you hunt for deals, but so you're the one who knows.
