Oh, AND... my friend's husband is kind of cheap. A great guy overall, but he doesn't always see the value in spending more upfront to get something that lasts longer, and he can "get by" with less stuff/more inconvenience than my friend, so sometimes they clash about stuff. I remember when he was single and could survive on just 2-liters of soda and loaves of white bread from the cheapest grocery store. Also he would take cold showers, with something in the pipe leaking and spraying him at a weird spot, rather than pay to have the plumbing fixed. And when he worked the night shift, he would rather sleep on a cot in his closet, than pay for curtains to put over his bedroom windows to block out the daylight.
More recently, his wife was discussing buying a new carseat for their child, who had outgrown his first one. The model she wanted was a bit expensive and she wanted to get two, one for each of their cars. At first he suggested only having one, in her car; and she said that would be really inconvenient, because that meant she would always have to be the one to pick up the child, or they would have to do an awkward vehicle swap. Then he suggested getting the expensive one for her car, and a "cheap" carseat for his car. Oh, boy. That works for so many things, but not carseats.
