Depends on how aggressive you are going to market. For example, at Farmers Markets I do one 8 oz sample of cubed cheese for every type I sell. I usually do 12 different types, so that's 12 sets of samples every day. I do 6 markets every weekend, so we go thru a LOT of samples. A store front presents a more difficult situation. You could put out just 1 or 2 samples every day, but the more samples you put out, the better your sales will be. And unless you have a lot of foot traffic, most of the samples will go to waste.
