What is valuable?

When I do classes I like to bring a roll of 2 part raffle tickets and an assortment of Andis trinkets to raffle. I bring along an Andis tote bag with logo tee shirts, tote bags, water bottles, clipper combs, etc. When I conduct the raffle it is interesting to see how the different groups respond to different items. By far, the most popular item is the little mini Andis Improved Master clipper key chain. It is likely the least expensive item in the pile. The only one that you cannot use to make any money, yet, it is the one they all fight over. Go figure. The magical power of the Andis name and brand and the enduring quality and reputation of the Andis Improved Master clipper goes a long way.
