Will New Limits on Amazon Prime Impact Sales?

Amazon is imposing limits on its Prime membership program that offers free, fast shipping for $139/year. As of October 1, 2025, Prime members can share benefits with only one other adult and up to four children in their household, through the new Amazon Family plan, which is replacing the Prime Invitee program. (Some additional children will be grandfathered in - specifically, up to four teens per household added prior to April 7, 2025.)

Prime invitees (those who share an accountholder's membership) will lose access to the shared benefits unless they are able to join an Amazon Family plan through that accountholder instead. Otherwise, they must create their own Prime account. If they don't, it could impact their shopping behavior on Amazon.

The company sent letters to Prime accountholders and their shared members (invitees) on September 1st to inform them of the changes - they were similar notices that shared a common subject line: "Important update to Prime benefit sharing." 

The following day, Reuters reported that this summer's Prime Day failed to meet last year's number (as well as Amazon's target number), citing non-public, "internal company data reviewed by Reuters," which it included in its reporting:

"During the four-day event, Amazon signed up 1.6 million Prime U.S. subscribers, exceeding an internal target by about 6%, or 87,000, the data showed. But in the three weeks prior to Prime Day, a closely-watched internal metric, Amazon registered 3.9 million new U.S. Prime members, 185,000 fewer than during the same period in 2024 and 193,000 below its goal, about a 5% miss in each case. Reuters was unable to review worldwide data and Amazon declined to make it available."

The number of new sign-ups Amazon attributed to its Prime Day holiday may have played a role behind the new limits to Prime membership. It would be interesting to know how many invitees will lose their membership on October 1st due to the new restrictions and whether they will be inclined to pony up the money for a subscription of their own.

Amazon is giving invitees an incentive to pay for their own account: 12 months of Prime for $14.99 (after the year is up, it reverts to $14.99/month). In a letter to those with linked accounts (invitees), Amazon said the promotion offering a year of Prime for $14.99 will run through the end of the year: "This special offer begins on September 5, 2025 and remains valid until December 31, 2025. You'll keep your order history when you sign up using your current account. Take advantage of this offer before it ends."

Consumers might see programs like Prime and Walmart Plus as ways to save money at a time of rising prices and tariffs, while others may look to save money by cutting such subscription plans. Their decisions may be shaped in part by their experiences during the pandemic, when there were shortages of paper goods and other essentials.

Coming right as the holiday shopping season gears up may also influence shoppers' decisions - and the one-time $14.99 promotion for a year's membership may also sway their decision.

Searching Reddit for "amazon prime" brings back numerous threads where people report they've dropped Prime - but posted months ago, prior to the changes to account sharing. 

Searching Reddit for "amazon prime family" brings back numerous threads from this week specifically discussing the latest change to the program. In addition to lots of questions from people about how the transition will work, posters revealed that they've shared Prime accounts with family members outside of their households for many years, such as the Redditor who wrote: 

"My daughter has the Amazon prime account, three other family members in two states use it. We all have our own credit cards in there. And two of us have our Alexa, etc on there. What a pain to de-tangle if that is what it means. I didn't get the email yet. Can anyone explain like I'm five? Thank you in advance."

Even if current member-invitees who are kicked off plans beginning in October don't all create Prime membership accounts of their own, they can still shop on Amazon. 

It's rather a shame we'll probably never see details of how the changes impact the number of Prime subscribers and how it directly impacts Amazon's sales.

Update 9/8/2025: An Amazon spokesperson provided us with the following statement:

"The Invitee program, which launched in the U.S. in 2009 and stopped accepting new invitees in 2015, enabled sharing of the Prime shipping benefit only and is being phased out. 

"Fewer than 1% of U.S. Prime members are affected by this change, and the majority of invitees can instead enjoy a broad range of Prime benefits with Amazon Family, including: fast, free delivery; access to exclusive deals and shopping events like Prime Day; movies, series, and live sports with Prime Video; Amazon Music and additional digital entertainment; access to a free Grubhub+ membership; and fuel savings at more than 7,500 bp, Amoco, and participating ampm locations. 

"Amazon Family enables Prime members to share a range of benefits with one adult - whether that is a spouse, family member, or roommate - and Prime Video and additional digital content like Kindle eBooks, audiobooks, and games, with up to four children in their household."
