Husbands for Sale Store

A store that sells new husbands has opened in Toronto, where a woman may go to choose a husband. Among the instructions at the entrance is a description of how the store operates:
You may visit this store ONLY ONCE! There are six floors and the value of the products increase as the shopper ascends the flights. The shopper may choose any item from a particular floor, or may choose to go up to the next floor, but you cannot go back down except to exit the building!
