I'll play.
I don't go in for candy much anymore, but jewelry and yummy smelling lotions are great. Ammo is a good choice too (5.56, 22LR, or 40 are always good bets).
Also, assuming my SO knew my sizes, lingerie of any sort would be richly rewarded. It's a gamble though--lingerie too small or too large will be regarded as an act of war and met with open hostility.
