With bargain hunting expected to dominate this year's holiday shopping season, more consumers are looking for discounts online, a survey finds.

The Monday after Thanksgiving, dubbed Cyber Monday by marketers, is poised to draw eight out of 10 shoppers to online retailers in search of free shipping, buy-one-get-one-free promos, and other deals, according to a survey of over 2,000 consumers by Shopzilla.

Forty-five percent of respondents said Cyber Monday is now their main holiday shopping day, compared to just 10 percent who said they preferred going to brick-and-mortar stores on the first Friday after Thanksgiving, or so-called Black Friday.

Most online retailers are tapping into that trend by offering savings and other deals, the Los Angeles-based comparison shopping Website reported.

Last week, BDO Seidman projected weaker sales on Black Friday this year as a result of the fragile economy.
