Is there a place where I can sell my stuff for the actual price? Ebony longsword for 20k? Or rather, where can I sell stuff where the person I'm bartering with has a load of $ ?

You can sell your stuff to Creeper at Caldera at cost price. He only got $5000. I suppose you'll need to do barter system to sell off all your stuff.

Or, You can download Rich Creeper Mod which got tons of money.

Though they won't give you anything like full value, the only place to sell REALLY pricey items is to the professional enchanters, right after you've paid 'em a ton to lay a spell on something of yours.

BUT you have to sell them some small item before you have the enchanting done, in order to get them off their 'set point' of cash, and after the enchanting you have only the balance of the day to make your other sales: they'll re-set to their nomal $s at midnight.

Oru

hi.

there is a creeper in caldera. it have 5000$, and there is mudcrab south-east to vivec. mudcrab have 10000$.
they give full price for weapons and armors (IIRC they don't buy gems and other stuffs). you have to repair the weapons/armor for full price.

mudcrab is supercool. i have ~700.000 gold at the end of the game.

Why would a mudcrab have 10,000$ ?

You could alway's ask it..
