I don't look all that often, but when I do - it is usually really expensive stuff, and sometimes extremely expensive.
Such as today, I bought my current car last July and today I'm browsing pickups, and seriously considered going for a test drive. I've lost the car battle twice, looks like I might be going for a third!
The problem is I talk myself out of buying the model I really want because it is too expensive... so then I settle on one that is cheaper. Then I think about the car I want and get something else but still don't spend the full money.
I'd save more money just by dropping the full $$ but I just can't!
