I'm going to start documenting my NPN successes, and failures, along with the amount of money I spend in stamps sending these things out to determine if it's "worth it" in the long run.
I'll need some help, though. I'm going to try to send out as many as I possibly can, from all sports. What I need, from those of you willing to help, is for you to PM me with all the NPN info that you can. If you open a product that has NPN info on the packs, and it's not too late to postmark the NPN request, please PM me the info.
If you'll let me know, too, I'll send you all of the ones I get in return.
