I don't know about that. How is this different from Costco selling a membership for a year? You've just paid up front for access to Costco for a year and now you are "pretty much locked in". Why doesn't a cookie company sue Costco for better placement the ability to pay for those cookies with cash directly to the cookie company? Those poor customers are locked into Costco and have to live with Costco's choices on which products to stock, where they go in the store, and pay for them through Costco checkouts.
