Costco Samples

I live in Canada and we do have Costco but I never go there. However, the grocery stores here do give samples of new products etc. from time to time and I do like to test things out but I don't go back for seconds. I don't like to be greedy and that is not what the samples are for. It is not a buffet it is just to try out the product and then if you like it you can buy some!
