25 cents is a lot. If the difference in location/quality/texture/etc. isn't enough to favor the $1 pizza, I'll buy the cheaper pizza. And I'm different than you, a slight difference in quality isn't enough to shift me one way or another, I need a reasonably significant difference. Anyway, if I eat only 200 slices in a year (not unreasonable) at the cheaper place, I can buy a video game (or something else for $50) that I couldn't have otherwise gotten (all else equal) if I bought the more expensive pizza every time. I don't see what's so amusing to you about saving money, even if $50 is a trifling sum for a programmer...
