Scroll of Spirit

About 27c on Beta · Alliance (9 hours ago), 25c on Beta · Horde (15 hours ago), and 67c on Beta · Horde (1 day ago), from player scans. A vendor pays 25c, so the auction house pays 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 5 brings about 1s 28c there, against 1s 25c at a vendor.
