UPDATE 9:15 a.m. EST: Cyber Monday 2016 looks like it was a very successful day for online bargain hunters, who helped retailers bring in over $3.45 billion in e-commerce sales.
Not only is that a 12.1% increase from last year's sales, that number jumps past Adobe Digital Insight's earlier estimates of $3.36 billion. It marks the largest U.S. online sales day ever.
What's more, these eye-popping shopping numbers show consumers are continuing to shift their spending money online.
And they're moving their shopping increasingly to mobile devices.
Shoppers spent $1.07 billion using mobile devices, slightly less than on Black Friday, but 34% up from 2014.
Other big winners? Walmart, Target, Best Buy and Amazon, where shoppers splurged on TVs and gaming consoles. Toymakers and beauty product sellers also saw healthy sales over the long holiday weekend, CNBC reported.
"Cyber Monday was one for the history books this year," Adobe Principal Analyst Tamara Gaffney said in a statement.
Read on for our original story below:
Cyber Monday is in full swing -- and if early numbers are any indication, online shoppers are on track to helping retailers leapfrog last year's sales milestone.
According to Adobe Digital Insights, the online shopping holiday has already brought in $540 million between midnight and 10 a.m. ET. Adobe's estimates call for sales to reach $3.36 billion in digital sales on Monday, 9.4% up from a year ago.
This data comes after a strong shopping weekend and a Black Friday online sales record.
Per Adobe, early morning shopping on mobile devices accounted for $205 million.
Of the $3 billion spent online on Black Friday, $1 billion came from mobile devices.
WATCH | Meanwhile, this year for shoppers it's been all about Black November. Retailers have been capitalizing on consumers' online shopping habits to catch them when they're in the mood to spend.
More Cyber Monday shoppers
The National Retail Federation (NRF) expects more than 122 million Americans to shop virtually on Cyber Monday, up from 121 million in 2015.
Black Friday accounted for an eye-popping $3.34 billion in online sales. Knowing some consumers are spreading their shopping budgets over a period of months, retailers have promoted Black Friday-level deals since early November.
Biggest sellers so far? Toys and tech
Adobe says the top-selling electronics over the weekend were the Sony PS4, Microsoft Xbox, Samsung 4K TVs, Apple iPads and Amazon Fire.
As for toys, Lego sets, Shopkins, Nerf toys, Barbie dolls and Little Live Pets made the list for top-sellers.
Amazon had said this Mermaid Tail Blanket was among the "most-watched deals" going into the shopping weekend. It's unclear how much inventory has sold so far.
