This is my first price suggestion on here, so forgive any mistakes I make. I have found these to be quite an interesting item to sell, since it is used by many Scouts and is proved to be useful in many situations.

Being sold in a meagre amount of 4 pages on Outpost usually in sets, parted or sold out.These are still possible to be found at 1.33 alone (in which case, is eagerly snapped up by investors or people wanting it for personal use). I have bought up quite a few of these though, and look to make a rec’s profit off these. If you check, none on Classifieds are selling for under 1.66.

Sold at ≥1.66 (time taken)

http://www.tf2outpost.com/trade/14728083 (4 days to sell 3)

http://www.tf2outpost.com/trade/15002479 (I took 3 days to sell 7, and counting!)

http://www.tf2outpost.com/trade/15046327 (Declined a 1.33 ref offer 2 hours after posting)

Will add more to the above section when found. Not many people are selling these, so it's kinda hard to say... :/

Selling for other specific items/games (notes)

Not really sure whether this is relevant, but these show the amount of Bats in sets, bringing individual Bat buyers an inconvenience
