Store Shopper - Shopping List app for iPhone and iPad

Store Shopper is a shopping list application specifically focused on shopping by destination. You dont create separate lists. Each item is assigned to one or more stores. Once needed items are selected, store based shopping lists are created automatically. When you are going to shop at a particular store you select it from the Shop screen. Any items you purchase while in that store are removed from all the other stores. For example, if you assign Butter to both Walmart and Target the item will show up in each stores shopping list. Checkout removes any checked items from the each stores shopping list. While this requires a little more setup than other shopping list applications the final result is much more efficient for people who shop for the same item in a variety of stores.
