In my family, stocking stuffers consist of socks & underwear, some candy, cards, any joke things like trick lighters, sometimes some magazines. DH gets hot sauce, nips of booze, and beef stick from Hickory farms, and magazines. Pretty much anything small that I see he might like that would be a hassle to wrap.
I like putting some surprising things in there too, that he won't expect. This year he's getting some nice shaving lotion and some honey dust
