Regarding previous suggestion: http://backpack.tf/vote/id/54dfdc27ba8d8809618b5121

and some replies that I need more proofs/deals. I have found another deal. But first thing first.

Just 4 of them exists. Just bought one for 1 bud + 8 keys - seller list price was 20 keys:

Seller: http://www.tf2outpost.com/trade/24957842 - without price, I bought from bp.tf classifields listing.

The second deal:

Unusual history: http://backpack.tf/item/3529830275

I asked seller what was the deal: http://i.imgur.com/OFIN2aQ.png

It gives around 20 keys - like mine.

Flat 20 keys should be fine for now.

I hope this time it will be ok :)

Cheers!
