most all trinket shops only carry 750 and the majority of the junk i want to pawn off on them is worth more than that. does anyone know who has the most money or the best places to sell? i hate having to wait 48 game hours for them to have money again and all three of my houses are getting seriously filled with stuff i don't want but also don't want to take the time to sit and sell.

which shops are the best?

Thieves guild definitely

If you put perks into the Speech tree you can invest in Riverwood Traders which will then have 10,000 gold.

That Lucan Valerius, he's quite a catch.

P.S. Even before you get that far in the tree, there's a perk that lets you sell any kind of item at any vendor which also helps in offloading. Generally speaking I find Windhelm and Whiterun are the best places for trading. Windhelm has two general goods dealers right across from each other (Niranye and Aval Atheron) and Revyn Sadri in the Grey District.

Thieves guild and Riverwood Trader are your best bet. As has been said above. The downside is that you have to invest in the speach skill or join the thieves.

It doesn't even matter really, just invest money, get the last thing in speech and get the thingy where you can sell anything to anyone.

This. It takes a bit of work but they'll have 4000 without any speech perks. Only downside is you have to do the quest. Not sure if that's against what you're playing or not.

Investing in riverwood is the best option
