LOL! This is what I do. All.The.Time.
Eat at home
Shop sales
Don't shop at all (when even the sales are too much!)
Cut Dh's hair (sometimes he gets a wild hair to wear it longer...my expertise ends when I can no longer use clippers)
Avoid pre-packaged meals (except the occasional pizza)
Make homemade refried beans (costs about 25 cents to make a whole ton of them! Costs at least a buck for a 15 oz can,kwim?)
Coupons, coupons, coupons. BOGO is your friend. :D
Wait to shop KOHL'S until you get the 30% off coupon. Then, shop the sale racks.
Be a minimalist when it comes to shoes and pants. I find I do well with < 10pr of shoes. Even that seems like a lot. Couple pairs of good fitting jeans, a few slacks, a few capris, a few shorts. Then you have coordinating tops galore!
Sell-donate-throw what you don't use, so you can get to what you have! (and then you don't rebuy it)
