NEW YORK (TheStreet) -- Cyber Monday online sales set a new record of $2.29 billion, up 16% from 2012, according to the Adobe Digital Index 2013.
About 18.3% of the sales were from consumers using mobile devices, an increase of 80% from last year, Adobe said.
The record breaking online sales Monday were in addition to record-breaking Internet sales on Thanksgiving Day and Black Friday, at $1.06 billion and $1.93 billion, respectively, according to Adobe data.
Total online sales from Thanksgiving through Cyber Monday surged 26% to $7.4 billion. While so-called "brick-and-click" retailers dominated the Thanksgiving weekend sales, Internet retailers, namely Amazon (AMZN) - Get Amazon.com, Inc. Report and eBay (EBAY) - Get eBay Inc. Report, generated the most sales on Cyber Monday, with a 42% share.
Wal-Mart (WMT) - Get Walmart Inc. Report said on Tuesday that its Web site had its best sales day ever on Cyber Monday though it didn't release specific sales numbers. Walmart.com processed more than 1 billion page views between Thanksgiving and Cyber Monday, the Bentonville, Ark.-based retailer said.
Walmart.com will offer 200 online specials every day through Friday, Dec. 6. The company is also offering free shipping throughout the holiday season on all orders of $35 or more. Online orders can also be shipped to local Wal-Mart stores and in many instances, be picked up as early as the same day.
Cyber Monday consumers shopping on their smartphones or tablets generated $419 million of sales yesterday, with tablets driving more of the mobile sales than phones, Adobe says.
Social media also contributed on Monday. Facebook (FB) - Get Meta Platforms Inc. Class A Report brought in two-thirds of the $148 million in social media-driven sales over the weekend (up 12% from last year), while Twitter's (TWTR) - Get Twitter, Inc. Report share rose to 9% (that's an increase of 24% year over year). Pinterest also saw strong growth increasing its share of referral traffic by 17% year over year, Adobe says.
"Retailers earned 10% of their annual sales in just the last five days, an increase of 26% (year over year)," said Tamara Gaffney, Adobe's principal analyst. "Sales from mobile devices saw the biggest gains with an 80% increase over last year."
ShopperTrak estimates that bricks-and-mortar retail sales over the four-day weekend rose just 1% as shoppers spent an estimated total of $22.2 billion. Retail shopper traffic decreased by 4%, to an estimated 1.8 billion store visits, the analytics firm said Tuesday.
While total in-store shopper traffic rose by 9.4% in the apparel sector, store traffic in the electronics sector decreased by 6.5% for that same time period, ShopperTrak says.
The National Retail Federation estimates that consumers, on average, spent 4% less than they did last year, on Thanksgiving weekend thanks to strong promotions and sales by retailers. The NRF estimated that shoppers, on average, spent $407.02 compared to $423.55 last year. Total spending for the four days is expected to reach $57.4 billion.
The NRF still expects holiday spending to rise 3.9% to $602 billion.
Adobe's online shopping data is based on the analysis of nearly 900 million visits to 2,000 retailers' Web sites on Cyber Monday and more than 3 billion visits since Thanksgiving Day.
