American Express has just announced that they will be doing their very popular Small Business Saturday promotion again on November 30, 2013. Through the promotion, American Express offers a $25 credit per card for spending at least $25 at a small business on November 30th. Registration for the promotion is required and is limited to a certain amount of total spots. Registration for this promotion is not live yet. You must register each individual card number in order to get the credit. Terms and condition are here.
My experience has been that every cardholder on an account is eligible for their own credit, in essence with 5 card holders you can get a total of $125 in credits. Here is my experience from the Small Business Saturday in2011.
