Successful selling of sets to a group is dependent on two principles:

Principle #1: “The more you show, the more you sell.”

If the sets are visible, you will sell them. The more visible they are, the more readily you will be able to sell them. (Note: even if you’re not able to follow the elaborate process suggested below, if you simply make arrangements to display the sets, you will also sell some. By the same token, books left in boxes in the dark recesses of a storage locker do not sell as readily.)
