I love camo. I have a standing item on my Christmas list that goes out to family: "anything camo".
I try not to buy much of it unless it is very specifically meeting a need for hunting, although I do buy some random non-hunting items.
Two items I have forbidden myself from buying is a camo deep freeze (by the time a deer gets near it, it shouldn't be able to discern that it is camo or not) and a camo lazy boy recliner (you can't hunt if you don't leave the house).
I have slowly (over 10 years) accumulated a nice kit of camo gear that I only use for hunting. It is easier to keep it separate and wash it separate so that I can control my scent a little better.
I hunt whitetail in the fall archery, but I am always hoping to get turkeys in range so going out without camo would be self-defeating. I do feel that camo has helped me get very close to deer and turkey on the ground. I was lucky enough to get a hand me down set of snow camo and that has been incredibly effective when there is snow on the ground. I doubt I would have ever bought that, but I love that I have it.
