GOT IT!!!!!
I never get anything but I got THIS!!! I ordered the DVD at the very beginning of January, still haven't gotten the DVD but i just got the mailer with the 20% off PIN!!!!!
I do not know if this has anything to do with it but....
I registered like I was a new guest with a new email & passcode, same name & same address, just a new email & password. I said I haven't been to Disney since 2000 (big lie) & I was thinking about going in November (true). I ordered the DVD then I priced out packages at different resorts & saved the offers.
I priced Deluxes & the Swan/Dolphin.
I did get an email from Disney Destinations thanking me for ordering the DVD then I got one yesturday about my free letterhead!!!!!
Hope this was the secret trick!!! Let me know if it works for anybody else, it can't hurt to try my method.
I have NEVER received a PIN from Disney, I have gone 7 times in the last 5 years so I figured it was time to start fresh & re-register all over again with a different email.
Good Luck!!!
