Prime Day began in July 2015 as a deals-filled, single-day celebration of Amazon’s anniversary. According to Amazon, Prime Day sales surpassed $3.5 billion in 2020, a 60% increase from 2019 and reflective of the larger shift to online-based shopping that accompanied the pandemic. Prime Day discounts take many forms, from Lightning Deals that require you to move quickly to grab that sought-after stick vacuum to deals that last the entire event. This year, we can expect a three-part musical event featuring Billie Eilish, H.E.R., and Kid Cudi. According to Amazon, all three episodes of the Prime Day Show will premiere June 17 on Prime Video and will be available.
