Love these ideas!
OK my new uber-frugal discovery is Kmart super double coupons. I have done a couple of the events now, and I basically use coupons for whatever is free. They will double up to and including $2 coupons. I keep a big give-away basket of extras for friends, and I donate whatever else I or others won't use to a local women's shelter. Recently I got free catfood, vaseline lotions, packing tape, clearance pine scented candles, swiffer stuff, crest toothpaste, toothbrushes, st ives apricot scrub, tons of makeup, juicy juice....I pay tax.
Couponing is pretty amazing!
I also am getting free/cheap stuff through couponing most weeks at Publix- they have great coupon friendly policies. My fave recent "frees" are Muir Glenn organic pasta sauce (I have a pretty gigantic stock of this now), halls vit c cough drops, 26 cent arm and hammer cleaners (their new green cleaners), and 18 cent Ben and Jerry's!
Oh yeah and Publix always has the mystery penny item on Sundays and Mondays... I try new stuff that way.
