Show HN: Budgetable (It's better than Mint)

I decided not to sign up for an invite but you almost had me. About 10 years ago or so a friend of mine and I were talking about creating something that analyzed what things you bought and then told you about where you can get it cheaper. At that time it really would't have been possible.

It's true I have seen deal alert sites but I thought you had the whole package here. I know you can't really find out what I bought at my supermarket by just looking at the credit card bill, but it'd be super neat if your site didn't tell me about the deals at supermarket A (I get that spam already) but instead find out that I buy skim milk, and let me know that supermarket B right down the road actually has it on sale this week so I should get it there instead. I want to keep buying the things I'm buying but be able to do so cheaper. Just like a gas app that finds the cheapest station, I want to know where the cheapest version of everything is that I buy regularly w/o having to look through ads or search myself or even tell a system what I buy. Build that and you got me. :)
