Being a chronic Costco customer I can say without a doubt that the tastings are going to significantly drive up sales on those days. I would be willing to say that 30% of those who taste will buy. Throw a coupon(discount) on top of that and that number grows.
It is amazing how many people put something in their mouth and then put the product in their cart.
