E-commerce behemoth Amazon (AMZN - Free Report) smashed records this holiday season with "billions of items" purchased in the period from Thanksgiving to Christmas.

More than 5 million new customers started Prime free trials or paid memberships globally and the number of items that were delivered with one-day or same-day shipping quadrupled compared to the last holiday season. Third-party sellers saw double-digit growth from the year-ago level, selling more than 1 billion items.

The top-selling product was Amazon devices including Echo Dot, Fire TV Stick with Alexa Voice Remote, and Echo Show 5 and the top-selling categories were toys and games, fashion, home, and beauty.

Per MasterCard Advisors' SpendingPulse, e-commerce sales surged 18.8% year over year this holiday season and represented about 14.6% of total retail sales. The growth is more than five times greater than overall holiday sales growth of 3.4%.
