Great question, so I asked Google and got this about rebates.
"Proof of Purchase: Companies need to know you bought their specific brand instead of a cheaper option.If a generic store receipt only lists a vague description, the company will usually deny the claim."
Also “Jose Cuervo is a bottom-shelf or “well” tequila, but most bars definitely carry it because it is the world’s most popular brand.” And Cuervo has numerous Top Shelf tequilas’ as well.
