E-commerce has reached a tipping point, according to a new UPS study.

An annual UPS survey shows that avid online shoppers on average made more than half of their purchases online in the last three months, excluding groceries.

Even for avid online shoppers, it’s the first time e-commerce passed the halfway mark in the survey.

The share of online shopping in the survey has been gradually creeping up, from 47 percent in 2014 to 48 percent in 2015, and 51 percent this year.

The survey indicates the increase of e-commerce among avid online shoppers, defined as those who make two or more purchases online in a three-month period.

It’s the fifth year Sandy Springs-based UPS has conducted a “Pulse of the Online Shopper” study, based on a comScore survey of more than 5,000 online shoppers.
