I've seen this label on coke cans at one point, and I was wondering: is this legally enforceable?
If it's not, is it possible for a retailer in any way to disallow the resale of an item purchased? Something like, I don't know, maybe a license you have to agree to in order to be allowed to purchase said item?
This comes in the larger context of these new tech releases (GPUs, consoles) and how the producers/retailers could legally prevent scalpers.
