is there any chance to sell stuff from standard on jsp.?
when i scroll down, only thing i see is mirror´s and divines beeig sold and bought

Very rare that something other than RAW currency getting traded here.
Depends on what you want to trade, i would suggest to trade it into divine orbs/mirrors before you sell it for FG.
Some people sell full builds but its not like d2(R) where people trade like shako / runewords for FG here.

Good stuff sells.

currency, alt arts, legacy items, items with legacy mods, 100% perfect gear
some of these sell more than others, but anything else doesnt sell at all

is there an easy way to link my stash and evrything
