Selling loot (wealth advantage and time spent)

[mirtexxan]

Hi guys,
I have a quick question about selling loot.

It seems that the rules highly suggest that the wealthiest delver sells the loot for the entire party... but are there any limitations in place? It feels to me very "cheap" to just pool character points into a single delver with wealthy and then the entire party will have a huge profit for this, especially if the wealthy PC is a team player.

And regarding another potential "limitation" on the inflaction of wealth... How much time does the selling takes? Does it depends on the loot being sold to different merchants? To the lump amount of loot to be sold in general?

So, how do you manage selling loot in your game?
