http://www.tf2outpost.com/trade/6759656 - My closed trade where I bought 2 apoco fists for 1.66 each.

Apologies for not getting very much proof from buyers, I couldn't find that much on outpost, and I dislike other trading sites.

Anyway, the demand for this item is just not very high. The heavy is not very popular amongest people who can actually afford to buy apoco fists, and most people prefer gloves of running urgently anyway.
