10 for $10

I went to CVS today and, while searching for discounted food, saw a "10 for $10" area. "Mix and match, 10 for $10," a sign read. It looked great until I realized that each individual item in the area cost $1 by itself. There was no discount-- I suppose the "mix and match" referred to the process of shopping in which a customer can buy more than one item at once and just add all the prices together for their final bill. Revolutionary, really.
