Won't do that this keys don't worth much. You have to be lucky to get "better" games for them let alone tf2 keys. I can throw in 1 sog in my offer, but believe me I am being generous with this offer.
SOG means sack of gems a lot of people use that as currency as well. On top if using tf2 keys. Someone people sell or buy them with their tf2 key as well.
