WIthout budgeting or really even cutting back severely, I spend about $100 less per month than the thrifty plan! We eat healthy, no processed food (it's more expensive) and some organics, although they are getting less and less with the economy tanking.
(DH needs to see that, he thinks I spend too much on groceries, when I'm spending $100 a week for a family of 4 plus a day care kid, 2 dogs, and a cat
) If I needed to, I could feed us for 1/2 that...for a little while, since we have a decent stockpile going. My bff (also on MDC) feeds her family of 3 on about $30-$50 a week. I'm amazed at that, especially since they eat a veggie, healthy, non-processed food diet.
We are in a high cost area of living (Orlando) and don't have access to farmers or cheap farmers markets (the one we have is MORE expensive than going to Target
Our $100 a week includes dog and cat food, toiletries, detergent and cleaning stuff (basically just vinegar and citra-solve).
