Sold for kill-a-watt brown bomber (49), 30 keys, 10 buds (~4.5) and a bill's (2.2) = ((49 + 2.2) * 0.9) + 30 + (10 * 4.5) = 121 keys

Looks like he traded some of the buds for keys same day. Buds were 5 keys on 11th and 4 on 12th and I can't really tell at what point the trade occurred so gonna call them 4.5 keys each, hopefully that makes sense.
