Bear with me here. This may seem like a huge leap, but it is needed

Thanks to BioPanda for helping with getting proof

Very few sellers/sales so this may be a bit awkward. While sellers above the current price are invalid, 2.5 keys goes very quickly.

Sellers/Sales at 2.5:

http://www.tf2outpost.com/trade/21137181 Been up for 1 day, offered 2 keys + s. rocket with parts, rejected, has another add

http://www.tf2outpost.com/trade/21181314 Spoiler, I bought this, but note it was only up for 2 hours

Sales:

http://www.tf2outpost.com/trade/20205748 2 for 3.5 keys, then rejected an offer of 3.5

Unsuccessful buyers:

http://www.tf2outpost.com/trade/20352259 around 2.5

Before you go and say "Oh he owns one downvote" keep this in mind: There is 1 or 2 pages on outpost, and 9/10 are selling for above 3 keys. The only sale I could find that wasn't outdated went for 3.5, and even that has been rejected as an offer. Any available for 2.5 keys has either been bought or has offers already.

Any feedback is welcome, and need be I will close this if someone can challenge this well enough

Let me know if you see any errors and I will correct them
