UPS' annual survey of 5,000 online shoppers had a few recurring themes that we are accustomed to hearing, but there were a few milestones:

The shoppers now made 51% of their purchases on the web compared with 48% in 2015 and 47% in 2014, according to the survey by UPS and analytics firm comScore Inc. The survey polled shoppers who make at least two online purchases in a three-month period, excluding groceries.

The shoppers reported that only 20% of their purchases were made in a store the conventional way—going to a store, browsing there and buying—down from 22% a year ago. Forty-two percent chose to search and buy entirely online, while the rest said their purchases were made by combining online and in-store shopping and browsing.

Consider the source of survey (UPS) and that the respondents are already online shoppers, but it's clear that shoppers are becoming more and more comfortable with shopping online. Less shoppers are just searching online and buying in-store...more willingness to press checkout with the mouse or finger and have the item delivered.
