I noticed while I was perusing the camping stuff that WM carries Celox (the 2 g packages) now. They have two different forms, a small FAK with one x 2 g pack and a small box of two x 2 g packs. The price isn't outrageous, about $6.50 IIRC for the 2 pack. I forget the price of the small FAK but it's packaged in a pretty slick little hinged plastic container that looks like it could be repurposed for many different applications.

I've used the 2 g packages and the stuff has worked well for me.
