The longest Amazon Prime Day yet will begin on Monday, July 16 and last for 36 hours through July 17. For many shoppers, it’s a day to finally snag that tech product or kitchen device they've been eyeing at a discount. But for others, it could lead to over-shopping, overspending and financial regret.

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.
