Amazon.com (NASDAQ:AMZN) just released some information about its annual best sellers. Some of the names were to be expected, such as those ubiquitous Apple (NASDAQ:AAPL) iPods and DVDs of the Disney (NYSE:DIS) hit Pirates of the Caribbean: Dead Man's Chest.

But perhaps the biggest surprise came from Sara Lee (NYSE:SLE). Its Douwe Egberts subsidiary makes single-serving coffee pods that became the biggest seller, most researched item, and most loved product of the season -- and of 2006. In December alone, Amazon said, enough pods were sold to supply the entire population of Austin, Texas, a city of 690,000.

We'll know in a couple of weeks how good Amazon's prime shopping season turned out, when the company reports sales figures for the December quarter and month. I'm looking forward to online sales totals for traditional retailers like Wal-Mart (NYSE:WMT) and Sears (NYSE:SHLD) to put the Amazon season into perspective. Among other pure-play e-tailers, Overstock.com (NASDAQ:OSTK) has plenty to prove after recently reporting its first-ever quarter of shrinking year-over-year sales.

Apple, on the other hand, already flexed its muscles -- maybe even a bit too hard. The influx of new customers armed with shiny new iPods and iTunes gift cards from their Christmas stockings overwhelmed the iTunes site, which slowed to a crawl for a couple of days.

Amazon is a far cry from choking its network infrastructure, though sales do continue to grow. It's just not the firehose surge of the late '90s anymore. Revenues for the holiday quarter rose just 17% last year, compared with 2004, after a couple of years in the low 30s. And if peak sales are any indication, this quarter should see another 17% gain. Hardly the stuff of legend, and perhaps a sign that the Amazon business model is maturing.
