Here are some interesting blogs on cutting food costs. There is the $1 dollar a day diet and $5 dollar dinners.
I also wanted to pass on a little linky for some very delicious but unusual snack mix Corny Snack Mix or known as the Corn Munch by Mrs Epi's family . It really is addicting and makes a giant batch. Just don't melt the white chocolate chips in the microwave both Mrs Epi and I didn't have much luck with the method. Thanks to Rock in the Dryer for posting that on her blog.
