I'm looking for a mod that saves a merchant's balance each time I exit a game. It's a little breaking that everytime I load up Skyrim, merchants get a new supply of gold and I just get richer and richer.

I know it's a strange request, I'm just looking for a way to make the game more challenging .

Thanks

Though I don't really see the problem, if it bugs you that you can save and load in front of a merchant and get rich by it, just don't do it.
I find it to be a bit like asking for a mod that remove the console comand additem that you can use to add [censored]loads of gold to your inventory.
