You just used a card that was registered last year ?
Did not use the card at Amazon recently
Did you get all your $25 credits last year ?
Think so
Had Shabbos Dinner with woman who works in Amex Marketing Dept, specifically the Twitter group for Amex Sync promos. She confirmed that the Amazon Sync promo would be coming back for "the holidays". Can't confirm that it'll be $25 off $75, but she didn't imply otherwise.
Shabbos Project encounter?
