AmEx is again having its Small Business Saturday promotion. It's not much money, but it doesn't require much work and it should provide a boost to your local small businesses (assuming they take AmEx cards). Here's an excerpt from the AmEx promo page:
Enroll your eligible American Express Card to GET $25 BACK ONE TIME WHEN YOU SPEND $25 OR MORE at a qualifying small business location on November 24th. Enrollment is limited so act early before enrollments run out. Corporate and prepaid cards are not eligible.
Refer to the AmEx Small Business Saturday promo page
for all of the details.
I've heard that the $25 statement credit is per card so if you have multiple AmEx credit cards, you may be able to get multiple statment credits.
