Clearly, this can’t be true, because one package contains twice as many pads as the other while both are the same price. The 100-pad box must be the smarter buy, or at least the marginally more sensible buy.
Update: Evidently neither we nor Ben know as much about gauze as we had thought. Indeed, the pads on the right are cheaper per piece because they’re a different type of gauze, and the “smart buy” is a free first-aid kit. Woohoo! Free stuff! You’re off the hook, Walgreens. This time.
