Product Availability Search is flawed

This shopping app works up to a point but searching for product availability for pick up is flawed. Even though you are given an option to enter your zip code to search rather than use location services (GPS), the system ignores that, and uses GPS anyway not matter the zip code entered. This locks the search to one store in some cases preventing you from finding the product in another store. For example, (keep in mind were talking about a rural area here) when Im at home and check product availability, this app allows me to search the availability of products in 3 stores. One in Des Moines and two in the KC metro area. When I go to work, about 30 minutes closer to Des Moines, the system locks onto the Des Moines store using the GPS and I am not able to see if products are available at the KC stores. Why prompt for the zip code if youre going to ignore it?
