Amazon typically plays its customer data close to the chest, but on Monday, the e-commerce giant let a few figures about its Prime service trickle out.
The Prime service, an offering combining free two-day shipping on many items with access to video streaming, had a "record-setting" holiday, an Amazon press release said. More than 3 million members joined the service in the third week of December, bringing its total membership to "tens of millions," it said.
Amazon also said it sold "millions" of its devices, doubling last year's device sales, although it didn't provide a more exact figure. Among the company's devices, its Fire tablet computer was the best-selling and was also the "most gifted and most wished-for" since its introduction 15 weeks ago, it said.
