A great way to acquire camo stuff is to remind everyone how much you LOOOOVE camo at Christmas time.
I generally get great stocking stuffers like hot pockets-style hand warmers and warm socks.
A good thing to remember is that "old" camo patterns and hunting equipment often go on sale after deer season. Also, check out warehouse outlets and army/navy stores. I've picked up some good stuff at a local pawn shop that sells army surplus.
