Gun accessories, alcohol, food, misc. electronics, medication when I'm sick.
I don't really buy a lot of car audio. Now that I am rounding out my home theater, computer, and other things I don't spend as much money on it. Usually, I will hold onto my money for awhile then go on a spree. I really need to open up a CD or something again to put my spare money in so I can't access it when I want to buy something stupid.
