Thanks @paulraphael and @Tri2Cook. Is the freezer the recommended place for storage? I would think that there'd be far too much moisture in there. In any case it sounds like you should get only as much as you need because they don't keep well.
I don't think humidity in the freezer is an issue, since the rocks are sealed in the foil. But lower temperatures slow chemical reactions, and frozen water migrates more slowly than liquid water ... so my assumptions is that the freezer would be better for longterm storage than the pantry. That said ... mine still didn't last too many months.
Edited to add ...
I think the freezer or fridge would be a bad place for storing a big pile of pop rocks if you were planning to take them out and use them frequently. For the same reason cold storage is bad for coffee beans. Every time you pull them out and open the bag, you'd be condensing moisture from the air onto the rocks and the inside of the envelope.
