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.

Sports apparel and gear reported a surge of 55% in the number of new customers visiting their sites, but the average dollar amount consumers spent per order slipped 3.1%.

Department stores also saw a 33% increase in new shoppers coming to their sites.

Kohl's ( KSS) saw its site crash over the holiday weekend due to an influx in traffic, but it was up and running in time for Cyber Monday.

"We expect to see one more spike in online spending when the final 'free-shipping-is-ending' promotions are announced," John Squire, chief strategy officer at Coremetrics, said in a statement.

Coremetrics gets its data from more than 500 retailers, including Nordstrom ( JWN) and Macy's ( M).
