Returning items sold by misstake

[Alexander4840]

I recently sold a BOE weapon i was going to use for a higher level and some heavy hide i needed for leatherworking. Is it possible to get them back?
Buyback option is ruled out. too much was sold after the important bits.

The only options for you are:
1. Buy the stuff on AH
2. Cross fingers and start grinding
