Ok, second suggestion so go easy one me, plenty of sellers for 2.33-2.66

EVIDENCE:

http://backpack.tf/classifieds/search/Genuine%20Pip-Boy - Nearly a page full of classifieds for 2.33-2.66

http://www.tf2outpost.com/trade/12382072 - Guy selling for Spreadsheet price (2.66) 3 Unsold at 2.66 (Check his bp)

This is really all the evidence I could find, most of the other pages were 3 refined. So, hopefully, that's enough evidence, if you guys have more evidence please post it in the comments and I will add it here.

More evidence from the very nice NecroTed:
