Once at a local gun show, the owner of the shop I worked at and I displayed some video tapes we had received from Federal ammunition. The tapes were free. There was a nice sign by Federal stating that.
After about 10 people asked how much they were, we started to play around. We put up a sign that read "Free video tapes..$5.95 each, 3 for $20.00 "
I swear to you that at least 10 more people tried to buy the tapes from us. A couple of them even tried to talk us down from $20.00.
