Product demonstrations are one of the top marketing strategies of all time. It's the whole try-it-and-buy-it mentality, perhaps with a little sales pressure built in. Not surprisingly, a recent study concluded that in-store cosmetics demos really do work.

In fact, at a Neutrogena makeup event held recently at Meijer stores, of the 67 percent who previously had not tried the brand, over two-thirds made a purchase right then and there. What's your experience with sampling events? Do you "brake for demos" are you not easily wooed by the claims of the presentation?
