I stopped going to stores for recreation- like to kill time or 'just look around'. Got off all email sales lists; when I go out to eat I only get the main course- no apps/deserts/drinks; and for me, using cash = spending less on variable expenses.
Even though I live in a tiny place, my next plan is to get a small chest freezer and buy meat in bulk. After pricing it out at a wholesale club, it really will make a difference.
