This leaves 18 days per year to buy things, each 20 days from the last. Do you grow your own food, or do you eat only nonperishables?

I shop for groceries about once per month, to buy food in bulk then freeze bread, meat and veggies. I grow some veggies in the backyard during the summer. I'm not the healthiest eater, mostly I just hate shopping. This gives me 6 misc days to buy gifts for birthdays and things.

I guess this doesn't count jumping on the odd humble indie bundle.
