Well here is my own list, jumping in!
SNES GAMES! Already have Super Mario World, Donkey Kong Country 2, Zelda and Mario Kart. The wife and I have been playing the hell out of them!
Ambi AR-15 selector switches and charging handles (ebay cheap is fine)!
Left hand holster for an M&P 40 handgun.
Interesting or old watches (Russian watches are cool).
Black or grey ankle length sport socks (hey, I need some lol).
I like knives a lot.
Been looking for a white camouflage ball cap, like the Kryptek ones with the velcro on front for a flag.
Metric impact sockets, in case you happen to have old ones laying around. I keep chewing up my standard ones in my air ratchet.
Remote control helicopter! The wife bought me a cheap one last year and I probably enjoyed it the most of my gifts until it finally died.
That's all I can think of for now. The bigger items are only if you find something usrd or have extras laying around, don't spend a lot!
