I can get 4 avocados for $5, a loaf of good sourdough for $5, and a dozen aggs for $8. $18/week ($3/day) and I can eat a healthy breakfast of avocado toast with 2 eggs every day.
That $72/month is what's breaking the bank, not my $2500/month rent.
Yeah they can be finicky. I live in the mountains in CA and they're definitely fresh, but you can tell they've travelled and the altitude here turns them shitty real quick so it's a delicate balance of getting just the right ones that'll be ripe at the right time in sequence to eat before they go to hell the next day.
