Edit: there was another sale this year on March 2019 but I've excluded it as it seemed a bit too far away from the price range of the other 2 sales.

Sale 3: Strange Purple Confetti Tundra Top (21 keys)+ Cloud 9 Whirly Warrior (22 keys)+ DBD Buccaneer's Bicorne (23 keys)

Cheers.

Let me know if I should include the 3rd sale btw, not too sure if I should or not
