I love that it can help us figure out which stores carry our products so we don't have to drive around looking for them! It is helpful when you need an item right away but do not want to run into traffic or spend too much time searching for what you are trying to find.
If they had more categories of items then maybe this would be better as sometimes there isn’t anything available within their database (or very limited) if say you wanted something specific like canned vegetables. This lets me know exactly where my local grocers stock certain things without having to look at multiple websites one by one.
