Got this via an email from Disney Channel (never watched it in my life, but they give stuff away!), title pretty much says it all! To get the code needed, just go direct to the page for the special (http://promo.snapfish.com.au/disneychannelfanfest/disneychan…) and then fill in your details (either as a new user or log in), and they'll give you a unique code which you then enter on the next screen - make sure you copy & paste it as otherwise you'll have to go to your email a/c to get it.
Not a mickey mouse deal. Might sound a bit goofy, but it's great for your photos of pluto. No more puns or I'll have to duck.
Thanks a lot OP. ;-)
