> Does anyone argue that a grocery store is using, much less abusing, its monopolistic power by doing that? No. I do. Especially with how common it is for a single chain to have over 30% market share in some area. Often the chain's only contribution is packaging someone else's product in their own branding, so independent brands can't build consumer trust. And in my experience, they make sure the store-brand product is always well stocked, while others are allowed to frequently run out. Even when, if you look at the fine print, the manufacturer is the same.
