You guys are trying hard so I'll give you a +6 on the cheap scale, but SD gets a +2 with only credit card hoarding.
My folks were both raised in the Depression era. They reused everything and didn't use a trash service as they burned it. Had me milk a cow because mom didn't want to buy unnecessary items. We butchered a steer and/or a pig once a year. Mom bought our clothes from Woolworths 5 & 10. Some of the crap was to embarrassing to wear. We didn't get new shoes until they were coming apart. As far as my mom was concerned, we were still in the Depression.
