In an effort to support small business around the country, American Express has announced this year's Small Business Saturday. American Express credit card holders can benefit as well. On Nov. 26, the day after "Black Friday" which is the biggest shopping day of the year, anyone with a registered American Express credit card can earn a $25 statement credit when they spend $25 or more at a small business, the company announced in a press release.

American Express members must register to partake in this promotion. Registration started Nov. 1 and is limited. No details were given on how many members would be allowed to register. Registration is available only through the Small Business Saturday Facebook page.

Eligible small businesses

According to the terms and conditions, an eligible merchant is an independently owned small business located in the U.S. Excluded are national chains, large stores, franchised businesses or government agencies. The purchase must be made with an American Express card; it may not be made with a prepaid card, ExpressPay or corporate credit card. The Small Business Saturday Facebook page includes a list of popular small businesses that users can search via ZIP code to find ones in their shopping area.

American Express first offered Small Business Saturday discounts in 2010. The current promotion is not available to any customer who received a $25 statement credit from the Small Business Saturday offer on Foursquare that the company ran earlier this year. Also, the offer notes that while the credit could be posted within five days of the qualifying purchase it could take up to two billing cycles for it to actually post to the customer's account.
