http://www.tf2outpost.com/trade/9731162 over 15 key offer still rejected (no paint)

http://www.tf2outpost.com/trade/9787522 got offered 16 keys (has paint)

http://www.tf2outpost.com/trade/9787322 looking for 16 like the other guy

http://www.tf2outpost.com/trade/9704557 put the price for 13 +sweets sold the same day

http://www.tf2outpost.com/trade/9510292 had a offer of 13 said too low (has paint)

http://www.tf2outpost.com/trade/9278174 he sold it to him for close to a big kill 15-16 keys

i havent seen anybody even think about going 12 keys, some people 13 keys but not that low

I can find more evidence but i am sorry if this is a bad price set. This is my first one so tell me on anything i can improve on.
