How long were you at Costco?
I do agree about the quantities though. For a single person, it doesn't make sense to buy the food when you can easily buy it at other stores for just the same.
I do agree about the Kodak Royal paper. Does Zellers print on Kodak or do you have to go to a Kodak store for it?
Did you check out the clothes? I always find that they have good men's clothes.
