Wish it understood zip codes better

Seems like it would be a great app if I could get the zip code to work. Could not get deals. Please try again...is all I get. I tried multiple zip codes of small and big cities and I could not get any deals in any areas. On a better note I can scan any food Im low on and it creates the grocery list for me. Hope yall have been luck with the app.
