WASHINGTON (CBS) — Tomorrow rounds out the start to the holiday shopping season with one million more people expected to shop online than there were on Cyber Monday 2015.

The National Retail Federation estimates 122 million people plan to take part in Cyber Monday 2016.

Online sales already hit a record high on Black Friday, a day where in-store purchasing is traditionally encouraged.

“On Cyber Monday, retailers deliver online discounts unlike any other day of the year—driving consumers to shop online no matter where they are or what device they’re shopping from,” NRF President and CEO Matthew Shay said. “Millions of consumers shopped over Thanksgiving weekend and reserved a portion of their budgets exclusively for Cyber Monday, knowing that there will be digital deals that are too good to pass up.”

According to NRF’s survey, 23 percent of Cyber Monday shoppers will shop from their mobile device. The majority of online shoppers however will shop from their computer or laptop at home, while 11 million will shop online while they’re at work.

Early-morning is still expected to be the busiest time for online shopping so don’t be too surprised if some of the sites with good deals are a little slower when you first wake up. If that’s the case, try again around lunch time when only 16 percent of shoppers are expected to be online, according to the NRF.

Besides discounted items, experts say customers can expect free shipping deals, free gifts with purchase and a “deal of the hour” at select retailers.
