Feedvisor is out with a new analysis of Amazon shopping habits, concluding:

• 85 percent of Prime members go on the site at least once a week, and 45 percent make a purchase at least once a week. That’s up from a year ago, when the numbers were 75 percent and 30 percent, respectively.

• 75 percent of survey respondents said they “often or always” check prices on Amazon before making a purchase elsewhere.

• 95% of Amazon users “always or sometimes” read product descriptions before buying products, and 90 percent said that a minimum three-star rating was required before making a purchase on Amazon.

• 43% of Amazon users said they would spend $10 for one-hour delivery, 32 percent said they would spend $10 for same-day delivery, and 20 percent said they would spend $10 for next-day delivery.

• In the wake of Amazon’s acquisition of Whole Foods, one-fifth of Amazon shoppers said they are more likely to buy groceries from Amazon, and more than a third said they would at least consider it.

• Just two percent of respondents said they did not find Amazon to be a helpful site.

KC's View: To me, these numbers show the degree to which Amazon is creating and cementing shopping habits that will be difficult for competitors to break. Not impossible, but difficult. And Amazon keeps working its advantages, never becoming complacent.

For example … The Hollywood Reporter says that Amazon, looking to promote its proprietary video offerings and attract even more Prime members, said yesterday that its original series, “The Marvelous Mrs. Maisel,” will be available this weekend to anyone who wants to watch it on the site - Prime membership not required.

“The Marvelous Mrs. Maisel” won two Golden Globes last weekend, for best musical or comedy TV series and best actress for star Rachel Brosnahan. Set in the late 1950s in New York City, the series is about a housewife and mother who finds her voice as a stand-up comic. When I reviewed it here, I raved about it - the writing, performances and production values are stellar, and if Amazon wants to put a foot forward, this is a good one.

Amazon has said, by the way, that more than half of U.S. Prime members who finished the series binged it within three days.
