Amazon has been viewed as one of the winners of the 2009 Christmas season
Online retailer Amazon reported a 68% rise in net profits for the first quarter of the year to $299m (£194.5m).
Turnover was up by 9% to $2.2bn, while total sales jumped by 46% to $7.13bn - more than expected by analysts.
However its forecast for the April-June period were lower than what investors had hoped, and shares in the firm fell 6% in after-hours trading.
Its Kindle electronic reader has helped sales but it faces a market share battle against Apple's new iPad.
Amazon will start selling the Kindle at some Target stores later this month. It can only currently be bought on the Amazon website.
