You’re OG comment insinuated that eating plants is cheap, yet you didn’t take into account the possibility that you either a) make more than others. b) live in a lower cost of living area than others. c) live in a great area that has many options for food diversity. d) that every store near you always has stock of everything you want and maybe other places aren’t so fortunate.
Our area is so over populated, we have to go to like 5 grocery stores throughout the county every week to get everything we want/need.
Maybe don’t be so close minded and consider that where you live and what you pay is available to everyone.
