Good point. I ran into a situation where I got my test strips from a mail order company. They sent me a free meter and their version of a premium test strip. I got a 3 month supply. I paid my portion in advance. It was the worst meter and test strip that I have used. The company would not trade the strips for a different brand. I ended up buying another test strip at retail price. I thought about selling the unwanted strips on ebay but I am not sure I want to go through the hassle.
