Journeyman's Backpack

About 19g 97s on Beta · Horde (5 hours ago), 19g 98s on Beta · Horde (22 hours ago), and 11g 99s on Beta · Alliance (23 hours ago), from player scans. A vendor pays 62s 50c, so the auction house pays 30.4× 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 18g 97s there, against 62s 50c at a vendor.
