so the thing was "4 for $5" and they each cost 1.50, so it's .25 off per bag, right? And the "you save:" thing said $1.00. And I called them over because, despite the fact that I had just explained the situation to my friend on a different item, I forgot that it was counting all four bags. So when they came over they said I was saving 25 cents per bag, and that it's so tiny why am I making a big deal about it? I asked what would happen if I bought 5, then it would be a bigger deal, and she said I would be saving 1.50. That's what I said "what are you talking about" on and she snapped and I just walked away laughing because I realized what I just did.
