$29.99 / $1.81 = 16.57 keys ~17 keys

Sales at 10, 12, 16, 17

Tbh I have my doubts about that 16 key sale being 16, since I honestly don't think a bot owner would really list an item 6 keys lower than what they paid.

Gonna go with 10-12 keys here, the 17 key sale was mp and looks out of place with the amount of lower sales
