Just last week I put the posted a very similar post! I'm Canadian too so I didn't know where to go. I was going to just use my rewardzcard at guest services at Disney, but I was worried the card wouldn't work by then. I'm sorry to say that I couldn't find anywhere on the web to buy DD's with the rewardzcard. If you phone Disney directly, they will ship them to you for a $10 fee but I decided against that. Instead, I used my card to buy a Sears Certificate for here in Canada. Wish I could help you more. Good luck!
