There is a bigger market for these than normal Napalmers yet the are more of them in existence...

Classifieds (As of 4:30 PM EST):

1 at 2.33, and 3 at 3 http://prntscr.com/6edr6b

There are literally only seven sellers on Outpost, only one of which that is really valid.

Seller at the current price:

http://www.tf2outpost.com/trade/25314166 4 ref (A whole well-aged 7 minutes :P)

Seller:

http://www.tf2outpost.com/trade/25261109 2.66 ref

Recent sale:

http://www.tf2outpost.com/trade/25241558 3 ref

As 3 ref still occasionally sells, but 2.66 ref has remained unsold, the range 2.66 ref to 3 ref should suffice.
