My grocery list app was lying to me for 8 months in Spokane

I kept wondering why my budget said I had $40 left for food but the cart always rang up $75. Turned out the app I used was counting sale prices in the estimate, not the regular shelf price. Last Tuesday I finally compared the total before checking out with the app's guess and the difference was $23 on one trip alone. That tipped me off that I'd been overtrusting the tech and underlooking the receipt. Now I write my list on paper and rough add by rounding up each item, takes 5 extra minutes but I've stayed under $300 a month for two weeks straight. Anyone ever caught their banking or list tool doing this kind of silent math?

Did you check if the app was pulling sale prices from a store in a totally different zip code? Because that happened to my cousin in Tacoma, the app kept showing Seattle deals and it messed up every single estimate for months.
