Once you’ve allowed yourselves a short time to recover from Black Friday, Facebook and American Express are teaming up to promote Small Business Saturday.

As part of Small Business Saturday, the social network and the credit-card company offered $100 in free Facebook ads to local businesses, which, unfortunately, have all been claimed.

Customers are not left out in the dark, however, as they can receive $25 credits on their American Express bills by registering valid cards via the Small Business Saturday, and then using those cards to make purchases at small businesses this Saturday.

From the Small Business Saturday Facebook page, which has more than 2.4 million likes:

First there was Black Friday, then Cyber Monday. November 27, 2010, was the first ever Small Business Saturday. Small Business Saturday is the day we celebrate the Shop Small movement to drive shoppers to local merchants across the United States. More than 200 organizations have already joined American Express OPEN, the company’s small business unit, in declaring the Saturday after Thanksgiving as Small Business Saturday.

Readers: Will you take advantage of this offer and add small businesses to your shopping lists this Saturday?
