Better known are its compatriots Black Friday (11/25) and Cyber Monday (11/28), the two bookends that begin the holiday-shopping season. But American Express’ Small Business Saturday (11/26), which returns for its second iteration this year to bring awareness (and hopefully, customers) to local businesses, may be the weekend’s best shopping bet. American Express is offering Rewards Points to its customers who shop small on Saturday; and many retailers are offering promotions of their own to sweeten the deal. One is Maria Cornejo, who is planning a gift for those who shake off the post-Thanksgiving haze to make it into one of her stores in New York or L.A. Spend $500 on your Amex card, and receive her hair-print (above) or book-print silk scarf. Small business is at the heart of Cornejo’s operation. The designer spoke with Style.com about the challenges and rewards of staying small.
