Honestly, the app function is fine with the caveat that it never seems to be updated with the store's inventory. With supply chain shortages, it's extra frustrating, I'd rather make the selection myself of a substitute item or not add it rather than get text after text and calls from my store telling me they are out of a product I ordered. It makes it where I have to be on my phone waiting to respond to their questions and the whole point was to have them grab everything for me.
