Where should you go if ur a journeyman in mercantile and u need to get rid of things like glass?

Oblivion i assume ?

Just go to the nearest town and find either a fence (if your with the Thieves guild) or a general merchant. Somehow it's no problem to sell off more stuff than they have cash in their possession. Maybe that's a bug ? If so, i don't really mind, it saves me from a lot of extra traveling.

I sell pretty much all my stuff at the blacksmith in Anvil, right across from the Fighters and Mage's Guilds. I end up going through there alot, and it's right near a quick-travel point. He'll only buy weapons and armour though.

Thanx but which merchant has the most gold in the game, due to the fact im trying to get expert in the skill so i can pick how much money they have on them

The merchant GP listed the amount that the merchant can spent on one transaction\item. So, if a merchant has a 800gp and you have 5 rings worth 800gp, you'll get the full 4500gp. But, if you have 5 rings worth 2000gp each, you are still only gonna get 4500gp out of the deal as the merchant can only offer you 800 per item. Doesn't make any difference in the early levels but after about lvl 15 you start to find items in the 4-6 range fairly regularly. Sucks to get short changed.

The highest I've seen so far is 1200 (if I remember). I think it was in a district in the imperial city (not the merchant dist though).

I may be wrong, but I believe the amount they have
on them is what you would steal off their dead
bodies, if you kill and rob them. That was something
I read on another forum and I've not killed a
merchant or store owner so I don't know if this is
true or not. Save a game just before killing one and
see if he has that much on him/her. Then reload the
save just before you killed him to avoid the fines.
