Well, it turns out the Walmart app (as does every other iOS app I use for local shopping) works just fine for searching in-store products and *without* any ridiculous requirement to create a user account and log in... Sadly, Im a lot more inclined to shop at that dump now instead of Target... plus its a little closer, anyway.
Target app now requires users to create and log in to an account just to use it for anything at all--such as to search ones local store for a product availability and location... even to just view store hours. I cant imagine this will lead to anything but a decrease in sales, if anything. Ill give it one more update (or two at most) to remove this foolish requirement before deleting the app and either trying a mobile browser, or simply heading about the same distance in the other direction that "other store" (gasp).
