When contacted about the Amazon Prime Day outage, the company said that some customers were having difficulty shopping, and it was working to resolve the issue quickly.
Amazon itself hasn't disclosed specifics, but Feedvisor's estimates are based on results from its clients.
"We have been humbled by the response from Prime members to Prime Day in Australia, with demand exceeding our expectations, and sales surpassing Boxing Day on the first day", says Amazon Australia Country Manager Rocco Braeuniger.
"For all the hype about Whole Foods, the grocery stuff on sale was less appetizing", said Sucharita Mulpuru-Kodali, an analyst at Forrester Research.
That put Amazon in the doghouse with upset customers, many of whom have gone on social media to complain.
Prime Day starts Monday afternoon.
According to data provided by Amazon, some of the best-selling products include the company's own Echo Dot device, Kindle Paperwhite, Huggies nappies and Finish dishwasher tablets. For some, clicking on various promotions just brought the person back to the home page.
The problem is most likely a bug in a software update that should be fixed within hours, said Antony Edwards, chief technology officer at Eggplant, which monitors website performance.
Like we said, there are over ONE MILLION deals on the site today.
If you haven't finalized your Prime Day shopping, be sure to check out all of the best deals that are still available and get it done before the event ends.
Packages move along a conveyor belt at the Amazon.com Inc. fulfillment center in Robbinsville, New Jersey, June 7, 2018.
Prime Day also usually helps boost the number of Prime memberships.
Yes, they sure did. Yes, there will be Black Friday and Cyber Monday, but wouldn't it be nice to get the shopping out of the way now?
