Bury them is a great idea so long as you bury them deeper than the frost line. The only prob with that is you could break them when digging them back up.
I read a post here a while back about a dood who found a cure jar from 2 years ago. He said it was mega kick ass. I store my shit in mason jars way in the back of the pantry. A cool, dry, dark place. They are now about 6 months old and everytime i open a jar, it smells as fresh as the day they were packed.
I dont put them in the fridge. Waste of space, plus the light going on and off all the time. Plus when someone goes to get a drink, i dont want them messing with stuff that isnt theirs.
