A new survey reveals the downside to how easy it has become to go shopping online—it's hurting some Americans’ finances. 

With the holiday shopping season in full swing, Stagwell’s Harris Poll released the highlights of the survey done with Nerd Wallet. 

The survey, of more than 2,000 adults in October, found that 22% have made impulse purchases that have significantly affected their finances in the past 12 months. 

And 16% have spent more on impulse purchases than they put into their retirement accounts. 

40% of young people who are feeling financially squeezed attribute it to their excessive spending on non-essentials.
