Walmart doesn't also have the ability to make buying the good from somewhere else inherently more difficult. It would be the equivalent of Walmart paying someone to stand in front of Target stores claiming to be an expert on the product you want to buy and saying "You know, the Target version of this product is very unsafe. You should really, really consider getting it from Walmart. I'm going to body block you from entering the store because I'm worried about you buying it from over there." What do I mean by that? Gatekeeper.
