NEW YORK ( TheStreet) -- Cyber Monday pumped up the volume on an otherwise middling kickoff to the holiday shopping season. Online sales jumped 14% on Monday compared to the same time last year, according to Coremetrics, a Web analytics firm. Consumers also purchased 30% more items than they did in 2008. With the Internet comprising about 10% of total holiday sales, these online sales are slowly but steadily gaining in importance. In comparison, Black Friday saw 195 million shoppers visit stores, but on average each shopper spent $341.31, down about 8% from $372.57 last year, according to the National Retail Federation. Amazon ( AMZN)and eBay ( EBAY) were in the spotlight yesterday, as the two major retailers without brick-and-mortar locations. Overstock.com ( OSTK) said its Monday sales were about 10% above their record-breaking Friday levels, the Wall Street Journal reported. Clothing and jewelry e-retailers were the most popular destinations, which bodes well for companies like Blue Nile ( NILE). Apparel companies saw the dollar amount consumers spent rise 26.4%, while jewelers jumped 14.3%, according to Coremetrics.
