Going with 65

Technically, this sale would be 64 after rounding, since the high-end of the Moon Prancer's is actually 68.5, which would give a median of 64.25, however, the low-end of the Moon Prancer's is based off of a seller rather than a sale, so I'm going to leave this at 65. (also, 65 is much neater to me :P)
