According to the report, this is the lowest monthly growth rate since the company began tracking online commerce in 2001. The lower spending comes from mid to lower income segments -- those with incomes under US$50,000, according to ComScore.

Households with income between $50,000 and $100,000 showed a spending gain of one percent, while those making at least $100,000 increased their spending by 14 percent.

It's no surprise that concerns over the financial markets grew from 14 percent in July to 49 percent in October.

Retail spending has fallen every month since April 2008 where growth was 15 percent. May (12 percent), June (11 percent), July (8 percent), August (6 percent), and September (5 percent), all lead to this month's lowest rate.
