Yeah, and you can wait for two days and the shop will restock. When I'm selling my alchemy potions my routine goes like this:
Buy all lockpicks, alchemy ingredients, and anything in misc that I want.
Sell potions until shop is out of money.
Wait 2 days.
Repeat.
I'm sitting at 20k right now with probably at least 5k in potions and the ingredients to make a lot more. I need to put more effort into getting Giant's Toes though.
PS3 version, krizz. and I didn't really like Skyrim in 3rd person much. Didn't feel right to me.
Point was that you can take it out of first person. I wouldn't play it in third person either. I only found out while trying to figure out what keys did what. (I couldn't figure out auto-run for a while)
