Fine Shortbow

About 39s 0c on Beta · Alliance (4 hours ago), 57s 0c on Beta · Horde (10 hours ago), and 74s 0c on Beta · Horde (1 day ago), from player scans. A vendor pays 6s 36c, so the auction house pays 5.8× 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 37s 5c there, against 6s 36c at a vendor.
