E-Commerce, which grows by leaps and bounds every year, is predicted to have another banner Christmas season, according to the global research and advisory firm Forrester Research.

Sucharita Mulpuru, a leading expert on E-Commerce, says that online sales should reach $89 billion, an increase of 13 percent compared to the 2013 holiday season.

The reasons for shopping online are pretty straightforward, says Mulpuru. It's all about avoiding crowds, long lines and higher prices that are more typical of brick and mortar retailers.

However, if there is one drawback this year it's that Thanksgiving falls on November 27, theoretically giving consumers less time to shop, although many will have already done much of it by then.

The real problem with a shorter season is that it puts a greater strain on delivery networks such as Amazon that ship packages out to consumers.
