Brad, I just replied.
Chris, this is primarily an attempt to connect people that have extra cards with those that can use them.
Here's how the program works: Someone who has extra cards sitting around and is willing to pay the shipping to send them to a playgroup that could use them lets me know. I get them the address for a playgroup and have them send the cards. When they arrive, the playgroup adds up the total value of cards and reports it back to me. In exchange, I can offer a 20% discount on that value of sealed items or 10% discount on that value of individual cards.
For example, if someone donated 400 $0.25 cards (not the ideal donation, obviously, but it's just an example), that would total $100, and they could purchase $100 worth of packs for $80 or $100 worth of single cards for $90. I know it's not a huge discount, but it's a little incentive to help get cards in the hands of people that can use them.
