Amazon is facing technical difficulties on Prime Day for the second year in a row

  • Amazon faced technical difficulties on Monday during Prime Day.
  • Customers complained that they couldn't add items to their online shopping carts due to glitches on the website.
  • Amazon also faced technical difficulties online during Prime Day 2018, with experts estimating the company lost millions of dollars in sales.

For the second year in a row, Amazon is facing technical difficulties on Prime Day. 

Customers complained that they could not add anything to their carts on Amazon on Monday, during the company's 2019 Prime Day event. 

When Business Insider attempted to add items to the cart, we faced similar issues soon after 11 a.m. ET on Monday. The items were eventually added to carts after initial failure.
