Heavy Leather Ammo Pouch

About 1g 74s on Beta · Horde (6 hours ago), 1g 0s on Beta · Alliance (1 day ago), and 1g 0s on Beta · Horde (1 day ago), from player scans. A vendor pays 5s 0c, so the auction house pays 33.1× 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 1g 65s there, against 5s 0c at a vendor.
