Highest buyers I could find were at most 2 keys:

[url]http://www.tf2outpost.com/trade/6322643[/url] Brown Bomber + Salty Dog + Orange Painted Safe'N'Sound (barely more than 2 keys resell)

[url]http://www.tf2outpost.com/trade/6332573[/url] Big Country + 3 ref + 1 rec (roughly 5 ref)

[url]http://www.tf2outpost.com/trade/6194632[/url] 1:1 with White Paint (roughly 5 ref)

[url]http://www.tf2outpost.com/trade/6310159[/url] 1:1 with Outback Intellectual (roughly 2 keys)

Sellers:

Possible counter argument:

Still: Upvote

i AGREE WITH THAT. UPVOTE SIR

And sorry for Maj :D

You made a good point, these should not go over 2 keys since no one is buying them for that price

i will upvote
