I will only buy clothes from the clearance rack at Walmart, or second hand stores, unless I make them. The only allowable exception is work clothes for DH. He works outside, and takes Coumadin, so I spend what I need to so that I know he is always warm.
I also buy cheap, dry, pet food and mix in a small container of dry premium, to keep them healthy, and happy.
I also use cheap paper plates (with a holder) to keep energy costs down (dishwasher), then use them to feed the dogs, which makes their food smell like ours!
If we use a paper towel to dry our clean hands, we reuse it over and over.
