-Sale 1 isn't really bulk but I'm fine excluding since it is likely low anyway and it looks to have sold to a bot.

-Sale 2 isn't bulk, it sold with 3 keys for a stormy trucker's + some ref (~11 keys total): https://backpack.tf/profiles/76561198165205268#!/compare/1553472000/1553558400

-Sale 3 is 10 keys. Maybe you would know if you checked the other side of the compare like you're supposed to :P: https://backpack.tf/profiles/76561198404123953#!/compare/1553644800/1553731200

You're also missing sales.

-Untraceable: https://backpack.tf/profiles/76561198165205268#!/compare/1553558400/1553644800 https://backpack.tf/profiles/76561198093418155#!/compare/1553558400/1553644800

-Untraceable but if I had to guess the mighty mitre sold for keys and then they used those keys to buy this hat: https://backpack.tf/profiles/76561198093418155#!/compare/1553644800/1553731200 https://backpack.tf/profiles/76561198087448314#!/compare/1553472000/1553644800

-Untrace: https://backpack.tf/profiles/76561198110619795#!/compare/1550102400/1553731200 https://backpack.tf/profiles/76561198258680239#!/compare/1551916800/1554768000

Closing due to random omitted sales and not bothering to check the other side of the compare revealing the 10 sale. This should be 10-12.
