Black Friday 2018 is shaping up to be the best Black Friday that America has seen in years.

Total spend for Black Friday weekend is predicted to reach roughly $59.6 billion, according to estimates by GlobalData Retail. That represents an increase of 5.7% over 2017 sales, which would be the best growth rate in the US since the postrecession Black Friday boom in 2011.

“More people have already shopped than at this point last year, and their average spend is higher,” Neil Saunders, the firm’s managing director, said in a statement. “The numbers who say that they have yet to shop or that they have more to buy are also up on 2017.”

GlobalData Retail defines Black Friday weekend as lasting from Thanksgiving Day through the following Sunday. According to Saunders, growth is coming thanks to several factors. More people are expected to shop, including middle- and lower-class consumers, and shoppers are spending roughly 5.3% more on average.

Much of the sales boost is happening online, with more people shopping on their phones and starting to search for deals earlier than in past years.

Shoppers spent $2.4 billion online on Wednesday, a whopping 31.8% increase from 2017, according to Adobe Analytics data. By 5 p.m. on Thanksgiving Day, they had spent another $1.75 billion, representing 28.6% growth compared with last year.

“Black Friday is bigger than a 24-hour shopping sprint or even a week-long marathon,” Accenture Strategy’s Frank Layo said in a comment on Friday morning. “It’s turned into a month-long extravaganza which started with promotions just after Halloween, and will continue well after Cyber Monday.”

The importance of the Friday after Thanksgiving itself is weakening, as holiday shopping starts earlier and earlier. But the day many still view as the official kickoff of the holiday shopping season is looking like a clear win for retailers.

“Although the economy is strong and consumers are confident, the numbers are impressive as last year was relatively strong in terms of spending and growth,” Saunders wrote. “It also bodes well for Christmas as it suggests that consumers have yet to run out of steam.”
