At craft fairs I have a tester station set up with a bottle of each lotion and/or body butter in each scent that I am selling at that time. For my lotions, since I don't use pumps, I put a pump on each tester and I actually assist the customers with body butter samples by scooping a small amount onto a popsicle stick. I also do the same for lip balms. I place a small amount on the stick and the customer puts it on their lips using their finger. this has worked for me for quite some time. As for giving out samples, I only give out free samples of soaps at craft fairs. I normally have many baskets of those already packaged in a glassine bag, labeled with scent, ingredients and where to buy. HTH
