  • Amazon’s website had consistent issues during Prime Day, the website’s biggest sale event of the year.
  • Shoppers had issues connecting to the website for over an hour on Monday, causing many to threaten to cancel their Prime subscription.
  • Various estimates suggest the website downtime cost Amazon $US72 million to $US99 million.
  • Regardless, Amazon still made an estimated $US3.4 billion during the sales and was believed to have had its biggest Prime Day yet.

The website glitches and downtime that Amazon experienced during its annual Prime Day sale may have cost it more than just some unhappy customers – the company is believed to have missed out on tens of millions of dollars in sales.

Shoppers began having issues connecting to Amazon’s website and participating in its biggest sale event of the year shortly after it kicked off on Monday. Some frustrated customers, unable to access or complete purchases on the website, threatened to cancel their Amazon Prime subscriptions, which were required to shop with the sales.

Amazon acknowledged the issues, noting that “many are shopping successfully,” and it eventually got things running smoothly.

But the downtime is estimated to have cost Amazon $US72 million to $US99 million in lost sales, depending on whom you ask, according to the news website Axios. Digital Commerce 360 estimates the downtime cost Amazon $US72 million, while Love the Sales’ Liam Solomon estimates it cost Amazon up to $US99 million.

It wasn’t all bad news for Amazon, however, as the company made an estimated $US3.4 billion in sales on Prime Day sales. Regardless of the losses and server issues, it is still believed to be the company’s biggest Prime Day so far.
