Amazon said on Dec. 26 that it had a record setting holiday season for Prime, with more than 1 million customers signing up for the service in the third week of December. It said Thursday that it had a "record-setting" holiday season for Amazon Prime, "with tens of millions of members worldwide."
It said that in December, Prime was so popular that "Amazon limited new Prime membership signups during peak periods."
During the company's conference call, the big news was Amazon's announcement that it was considering a price increase to Amazon Prime. Amazon launched Prime nine years ago in the North America, but has kept the $79 price steady even as fuel and transportation costs have increased over the years. CFO Thomas Szkutak said on the conference call that given customers are using the service more, Amazon is considering upping the price between $20-$40 in the U.S.
Szkutak did not give a time frame for when that price increase would occur.
"It's a good time to be an Amazon customer. You can now read your Kindle gate-to-gate, get instant on-device tech support via our revolutionary Mayday button, and have packages delivered to your door even on Sundays," said Jeff Bezos, founder and CEO of Amazon.com. "In just the last weeks, Forrester, YouGov, and ForeSee have all ranked Amazon #1 - and we believe we're just scratching the surface of what world-class customer service can be."
