Walking around Walmart

Last night Scott went to Walmart at midnight in hopes to get a Wii for my parents. Unfortunately he had to wait to see if they had any, so he did some walking around and told me how many weight loss pills they had around there. Usually during the day they have so many people there that it's hard to see everything, but at midnight there's not hardly anyone there so he was able to see all fo their product and it was weird to see all of these diet pills. I guess it's quite popular among people these days to lose weight. I wonder if works??
