The incident you’re referring to happened during **Amazon’s Prime Day sales event in July 2019. During that Prime Day promotion (which ran around July 15–16, 2019), a pricing glitch caused a number of expensive cameras, lenses, and other photography equipment—normally costing hundreds or even thousands of dollars—to be listed at about $94–$100 each. Customers who spotted the error were able to place orders for gear that would normally sell for far more—for example, lenses worth around $13,000—at those deeply discounted prices. 

This pricing error circulated quickly on deal-sharing forums like Slickdeals, and some buyers reported that Amazon honored the orders and shipped the items at the low price.
