Here California, there is a civil code section 1723, which states, that a retailer must post their return police in a conspicuous place if is a policy which is limited to either no return, or exchange for credit…
I post this because, when you buy a bed from Mattress discounters, they give you a 120 customer comfort guarantee and give the customer the impression that this includes the entire bed, which of course is the base unit also. Well, they do not accept the base unit returns it seems but unless they post this discrepancy in the store, I think the law will be on the side of the buyer in California
