Businesses selling their goods on Amazon had their best holiday season yet, according to Amazon. The company has over two million third-party sellers on Amazon Marketplace, and unit growth from U.S. sellers grew over 40% year-over-year.

“We value the breadth and depth of selection that businesses selling on Amazon offer our more than 188 million active customers worldwide,” said Peter Faricy, VP for Amazon Marketplace. “The entire Amazon Seller organization is focused on helping third-party businesses succeed and grow on Amazon. We do this by creating a dynamic marketplace platform that helps every seller deliver the best possible selection, service and prices to all Amazon customers.”

Amazon says third-party sellers sold enough smartphone and tablet screen protectors to cover every NFL stadium four times over. That’s not surprising considering the amount of mobile device activations reported for Christmas day alone.

Interestingly, sellers also sold something like 50,000 Santa hats and 500,000 guitar picks. Amazon says sellers also sold “enough mustache pacifiers to give one to every baby born in Washington State next month,” and “enough tea lights to keep a votive illuminated continuously for over 200 years.”

Amazon says sellers using its various ecommerce services (like Webstore, Payments and Product Ads) set records in sales volume, traffic and services performance.
