Another data point of this working. I bought at $275 e-gift card on July 3rd. I received the $275 credit July 6th. The gift card came within about 20 minutes.
Slightly off topic, but does anyone know if buying an e-gift card will also trigger the credit on the spend $200 get $40 back regular Amex offer? I have that on my Gold Card but not sure if it will also work. Thx!
