Journeyman's Backpack

About 17g 99s on Beta · Alliance (38 minutes ago), 19g 97s on Beta · Horde (7 hours ago), and 19g 98s on Beta · Horde (24 hours ago), from player scans. A vendor pays 62s 50c, so the auction house pays 27.3× more.

No. It is in Classic Era too, with the same item level, vendor price and stack size.

Sell it on the auction house. After the 5% cut a stack of 1 brings about 17g 9s there, against 62s 50c at a vendor.
