This history is the May 4 $32.99 sale, the May 4 $20.50 sale, and the May 8 $32.99 sale

Sold for $32.99 on May 4, then I guess they hated it so much they put it back up for $20.50, which is when I bought it

Then I deposited it right away (I don't show up in history) and then it sold on May 8

There's no bot.tf cache, but both our buyouts were 18

And I don't know where the history is, but the May 13 $32.99 sale also had an 18 key buyout

(A different one from the above history)

Might be 18 keys, but histories don't match
