"In conjunction with the Retailer Rewards program, Wizards of the Coast will also release a new Internet Sales Policy on April 6. The new policy will have clear guidelines for online sales of Wizards’ product, and requires that retailers register with Wizards by signing an Authorized Internet Dealer Agreement."

Damn, I started commenting. What I really wanted to say was this: if you have purchased PDFs, heck if you have valuable data of any kind, from anywhere DO BACKUPS. Right now.

Doing backups is one of the least rewarding tasks out there, right up until you dump a beer into your laptop.
