I'm new and want to contribute, and I didn't see this posted when I searched the thread. Right now with an American Express Business card and the right sync offer, you can get $250 in Disney Gift Cards for $175, up to 5 different times. To do so, look for the "Stock Up and Save for Your Business" American Express offer under "Offers for You" in your online account.
After the offer is applied to your AmEx, buy $250 in Disney Gift Cards at Home Depot, up to 5 times in 5 separate transactions, and you'll get a $75 statement credit for each. I've already done this 3 times, and plan to do it 2 more to renew my Premium Annual Passport.
