QUICKBUYERS at 6 keys who resell for 7

http://www.tf2outpost.com/trade/8111280 Me (Haven't bought a s f sandvich in over a week; I only use this trade as a side thing while I sell my unusuals)

http://www.tf2outpost.com/trade/7928298 (has one in his bp)

http://www.tf2outpost.com/trade/8899601 (has one in his bp is selling for 7)

http://www.tf2outpost.com/trade/10257620 (has one in his bp)

http://www.tf2outpost.com/trade/10458892 (has 2 in bp)

Conclusion: This item is very hard to move at 7 keys and even lower. Quickbuyers are seldom successful at 6 keys however. I expect this to be a close suggestion as I couldn't find too many below 7 keys (presumably all sold).
