Okay so im getting very frustrated... I use OOO.. So there are many monsters, and dungeons have real loot to plunger...
Shops has a lot of expensive stuff to sell ( items that costs up to 100k gold)
And i cant sell my loot because shops has like 1k gold or 2k gold at the most. If you wait like a stupid idiot for a week until shops will have gold, then you are doomed to waste half of game's time by waiting!!!

And i dont even take items that are bad.Example: 10kg axe has to be worth 200gold or i dont take it. Im starting to pick items that are like 1:4 ; 10kg - for a 400k gold or more...
So imagine i plunder half of the cave, and i badly need to sell stuff, so i go to shop, then i wait for a week.. and by that time all monsters respawn.. bullsht...
Well in my case monster respawn is made for 2weeks.. But the damn shops...

Does anyone know a mod for a shops to have like 50k gold and refresh their gold each day, and to be compactible with OOO?? ( i also have living economy mod )
It doesnt mean i will be able to find that much loot, i just dont want that frustration...

I'd suggest a lower respawn. I use 5 days, personally. 2 weeks seems a bit long.

As far as shops and money, I'd suggest simply selling stuff and sell more of it. By mid levels, it doesn't matter because you have plenty of money and nothing to spend it on. I grab everything and sell everything except what I want to keep.

Oh, and also I'd suggest noting the max value for any merchant as you level up Mercantile. For example, if you currently have a merchant with good disposition towards you and offering good prices, and they have 1000 Septims max, don't sell them something worth 1500 even if you won't use it. Wait until Mercantile gets to 75 and you can invest in their shop, then sell them the more expensive item to get the most ROI.

That's just my advice, anyway.

Did you even tried OOO mod?
Did you even played oblivion? One dungeon might have so much precious loot you wont be able to sell it all...And you are suggesting me to sell stuff? And to rise merchantile(the most useless skill ever)...

@ the OP, may I suggest taking a look at http://tesnexus.com/downloads/file.php?id=25078, which does most, if not all of what Living Economy does, is compatible with OOO, and is entirely configurable? I believe you could configure EE to vastly increase barter gold for merchants, or at least tweak them so their gold doesn't go down after a transaction.

If you're just looking for a merchant with a lot of gold, you could try WillieSea's http://tesnexus.com/downloads/file.php?id=13935
