Best merchants to recharge items?

Sure, but all she had was a bunch of smithing molds and 4 fine steel weapons. I sold her a Bracelet of Beetlekind, it didn't show up, I bought a fine steel weapon and luckily it was her last one of that type; but the bracelet still didn't show up even though I had cleared one inventory slot.

Have had this happen before. Exiting vendor and re-entering vendor window will sort that out. Sometimes they will still be full and you'll have to buy more, sometimes your item will be there since there are no other items on them besides the one you just sold.
