I'm not trying to boast, but I think I do a pretty good job in budgeting & buying our groceries. I shop twice a month & spend $90-$120 for those 2 weeks. I just want to throw in that we live in a very upscale area; for instance the average townhouse without a garage or yard starts at $225,000.00 & average rent for a 2 bedroom apartment is $800-900/month plus utilities. To some this may seem low, and to others it may seem high, but to us it's life.
But, I have been following Crystal's blog at Biblical Womanhood & boy, does she blow me away! She's doing a series on supermarket savings, and you should check it out to get any ideas.
