Yeah, I got it too.
It is from Disney Destinations
You have to order it longer than 7 days before your trip
(they mention you already paid your trip so they know you cannot use it to pay part of trip off)
No food can be purchased
Merchandise only
No resort deposits or payments
Used Only on disney owned property, so some places at Epcot are not included, japan and china Morocco and all kiosks, no tours
Can't use any other discounts (like AAA)
They also give you a PIN to use to order it via phone.
Also, no recreation places or item, no face painting hair braiding and the list continued.
It said 395 for $500
OR 445 for $600
OR 1000 credit for 695.
If I knew I'd be purchasing a lot this trip, its a great deal but too limiting and too many restrictions for my tastes, so I am passing on it.
