Analysts will get another glance into the psyche of the American consumer tomorrow (Tuesday) as sales data emerges for “Cyber Monday,” the unofficial kickoff of the online holiday shopping season.

Initial results showed a 2% increase in online sales over Thanksgiving and Black Friday, and the NRF said it expects another 84.6 million people to take their bargain hunting online Monday. According to a Nielsen Online survey, 36% of consumers will spend half of their shopping budgets on the Web, up from 32% last year.

Internet vendors are prepared for the online rush by offering discounts of their own, as well as free shipping, to potential customers.

The NRF’s eHoliday Survey showed that nearly 84% of online retailers will offer a special promotion on Cyber Monday, up from 72% last year. Nearly 39% of online retailers plan to offer specific deals, while 33% will offer e-mail campaigns and 25% one-day sales. About 23% will offer free shipping on all purchases.

“Online retailers have been planning their Cyber Monday promotions for months and are eagerly waiting to debut these deals to shoppers,” said Scott Silverman, executive director of Shop.org, an online division of NRF. “As shoppers focus on price this holiday season, online retailers will be extremely competitive to offer the very best deals. Americans who are looking to put a dent in their holiday shopping will be able to find thousands of bargains on Cyber Monday.”

Of course that’s not to say it will be any easier for online outlets to draw a crowd. Consumers may be planning to spend a greater portion of their budgets online, but overall those budgets have shrunk.

For the first 23 days of November, holiday online spending reached $8.2 billion, a 4% decline compared to the corresponding days last year, when online sales hit $8.5 billion, according to online marketing research firm, comScore.

"There was an optimism going into the holiday season that online would weather the storm a little bit better," Jessica Ried, associate director of research for Resource Interactive, an online-marketing consultancy told TIME magazine. "But this year in November we’ve seen the first online sales decrease ever.”

“I don’t know that this is the only prediction to go by,” Ried added, “but a dire prediction from an organization as big as comScore does give retailers pause."
