According to a survey from the National Retail Federation (NRF) and Prosper Insights & Analytics, there were more than 174 million consumers in the U.S. who made purchases in stores and online during the Thanksgiving through Cyber Monday period. This number surpassed an earlier survey from NRF and Prosper Insights & Analytics that estimated 164 million shoppers for this period.

Average spending per person over the five-day period was $335.47, with $250.78— 75 percent—specifically going toward gifts. The biggest spenders were older millennials (25 to 34 years old) at $419.52.

The survey found that more than 64 million consumers shopped both online and in stores. In addition, more than 58 million shopped only online, and more than 51 million shopped only in stores. The multichannel shopper spent $82 more on average than the online-only shopper, and $49 more on average than those who only shopped in stores.
