I don't own a car anymore. I make do with my bike, however this probably won't work for most people's living circumstances.     As for grocery's my staple diet is bulk chicken and beef which I eat as a need. For grains I stick to rice and pastas. For vegetables I tend to buy large packs of frozen vegetables which I've found to be excellent value. Since almost all frozen vegetables are picked at peak ripeness and then flash frozen, the quality and taste are quite good compared to how fresh vegetables can get near the end of their life span.    I would love to get into an organic farm co-op sort of situation but there is just nothing offered near where I live. You are lucky to have that service offered.    It's quite easy for me to eat under 100 dollars a month with this meal plan.
