#1 Not advertising. Advertising is what you see before you enter the building. Some stores don’t even have shelf labels.
#2 Do you think someone can walk up to your garage sale and slap their own sticker that says $1 and demand you sell them a TV for $1? No, you can refuse to sell your own shit whenever you want. It’s YOUR shit. You can burn it in front of them if you felt like it.
