You can buy a fresh direct gift card and get the amex offer. Then you can use the gift card to buy wine or alcohol..
For example 2 bottles of macallen 12 year single malt after taxes is $152.40 After using the $50 off $125 (FD100) and buying a $100 gift card for $70, your total is $72.40 or $36 a bottle.
I got the "Great news! You just used your Amex Offer" email when i bought the gift card.
