DH and I have saved so much in 56 years by fixing a lot of things. Appliance store wanted $100 house call to fix the plugged up refrigerator drain tube - we replaced it for pennies. Same for kitchen range repair. He paid a mechanic work on our car 2x but it wasn’t right so he bought the parts & did it himself. It gave no trouble even when our son & grandson “inherited” and used it for a work car for 7 or 8 years. We hang ceiling fans (and they work !!). I could go on and on but you get the idea.
