Ah, updated thread. I updated my packaging too last year. I had kept boxes and boxes of carefully stacked empties in my attic, but finally just tossed them all in a dumpster. I saved a few in one box, and now I'm just keeping the backing and inserts like a lot of you guys. I slice the bubble off and get rid of the plastic. These cardbacks take up relatively room so its not that much of a hassle. I have them now in a few 10 x 13 envelopes. I imagine it would be easy to keep these in clear sleeves in a binder.
