I'm a guy who doesn't pay much attention to prices, and it isn't because I'm wealthy, it's just that I don't really care much about saving little pennies here and there, and also because I tend to buy on quality rather than price. So what I did today was actually very out of character.
I've been buying 6-packs of heavy-duty paper towels (the blue ones) at HD. Today as I was grabbing one I noticed they also had 3-packs, and I got curious about how much I was "saving" by buying the larger pack. Turns out the 6-pack was 10.98, and the 3-pack was 5.48. Hell, I can do arithmetic in my head, so I bought two 3-packs, and saved two cents.
