Choose an item you want to sell and get one or two staff to wear it with a sign … sticky tape, a stapler, a new pens, a new magazine. Since staff don’t usually wear products, the product should be noticed and, hopefully, purchased.
This is a crazy idea. I can’t think of anyone who would try it. I doubt I would. And that’s the reason to try – because it is so crazy. What’s the worst that can happen? – customers will laugh. And the best? They buy the product.
