Free samples may seem effective.
But from my personal expereince the reality I have find is that most of the people who take free samples are those who don't want to spend money on such products.
Almost everyone show enormous interest while getting a sample but after that few or none turn out to be customers!

During purchasing customers set up a hierarchy of values,quality wants, and needs based on experiential data, opinions, word-of-mouth references, and previous experiences with products and services. They use that information to make purchasing decisions. Free sample of new products contribute a great role on this situation.

Consider the last item customer bought either online or at a stand-alone store that time some factors considered by customer when purchasing that item. Tasting or using the free sample of the products influenced customer decision to buy that item over another. After that, if customer satisfied, he/she go to a specialty store seeking out this item or buy on a regular basis at a store  visit frequently.
