It's the moment we've all been waiting for. Today, the longest ever Amazon Prime Day begins. From Monday, July 16 through Tuesday, July 17, deals will be widespread across the site. But while deal days are an opportunity for consumers to snag items at low prices, they can also be a trigger for over-shopping.

Since the first Amazon Prime Day in 2015, the event has expanded from deals on the site to extra discounts for Prime shoppers who download the app, use Amazon Assistant, find items using camera search or shop at Whole Foods with an Amazon Prime Rewards Visa, according to Amazon’s website.
