I sent off for a form (emailed them and requested one) and got the ol' S1 flap in the mail a few days ago. Awesome for me as I was going to be a sucker and sell off my old set in favor of getting the new complete series boxes. REALLY glad it didn't amount to that, although I did get the set for like 160 or so back when it was new thanks to the DD sale, so it worked out very well for me.
Also, yeah, there might be a spot for the Plan included or it'll just be the individual release in the set. I dunno, either way I doubt they give you any discs, just the boxes.
