Cheap things you buy even though you can afford expensive ones.

[ski]

I can think of two for me,

1. Hotel Rooms, I don't understand spending a lot of money for a room when you're mainly using it while you're not even awake.

2. Flashy car, seems like a waste of money and mostly an image thing. I don't really see how an expensive car serves its functions better than a cheap but reliable one.

Others?
