With a quarter of holiday shoppers planning to spend more this year than last, retailers can start to celebrate. In its second year of research into holiday shopping plans, analytics company SAS polled 3,458 consumers in the U.S., Canada, the U.K., Australia and New Zealand. The U.S. led spending growth with 29 percent of consumers saying they'll spend more. Canadian shoppers, on the other hand, are tightening their budgets this year. Millennial shoppers (ages 18 to 29) are most likely to up their spending this year, while older consumers are tending to stick with last year's budget.

Holiday shoppers are expected to spend more this season, but it's where or how they plan to spend that should interest retailers, as Thanksgiving Day shopping and social media gain in popularity, according to a new study from Accenture.

Globally, this compares to 1.42 percent, a figure also up from the previous .94 percent average of all common retailers surveyed the previous year.
