Predictions call for $91B blockbuster holiday

Holiday sales could reach $91.6 billion this year, thanks to an extended season that has seen shoppers start earlier and end later.

Some 53 consecutive days are expected to ring up $1 billion in online sales each compared with 31 in 2015, according to Adobe's 2016 Digital Insights Shopping Predictions.

Cyber Monday will again be the biggest online shopping day of all time, generating $3.36 billion in sales with 9.4 percent growth. 

Thanksgiving Day sales will also be strong and are expected to increase 15.6 percent year-over-year (YoY) to $2 billion, but not reach the 25 percent YoY increase of 2015. Black Friday will grow 11.3 percent YoY (14.3 percent in 2015) to $3.05 billion.

Adobe claims to have the most accurate spending predictions in the industry, coming within 2 percent in years' past.

Shoppers will continue to use mobile devices to browse but turn to computers to complete sales. According to Adobe, there will be a 19 percent gap between visits and purchases made on mobile. 

"We expect to see a five percent spike in online shopping in early November and a record 24 percent increase in the last two weeks of December,” said Mickey Mericle, VP of marketing and customer insights at Adobe. "‘Click and collect,’ faster shipping and retail promotions starting earlier than ever are all contributing to the extended shopping season. Despite the uptick in sales we expect to see slower growth in total online sales this year."

Early shopping is expected to have a big impact this year with one exception: New research from the National Retail Federation found that consumers have paused much of their holiday shopping activity until after the presidential election.
