Item then went to 3 different inventories in the same day then 3 different inventories the next day, these can't be actual sales. Probably gambled. The user at the end is bptf banned for price manipulation and has bad reps about scamming, so excluding their trade too

September 12 2020: $50/1.88=26.60 keys

Excluding 26.60 because it is really close to buyers at 25.11-25.22 and is also older, probably sold quicker too

(If I can't exclude this sale just tell me in the comments and I'll wait for more sales)
