In the US, online spending across retailers surpassed $11 billion over two days, compared to last year’s Prime Day total online revenue of $10.4 billion, according to Adobe. Large retailers with over $1 billion in annual online revenue saw the strongest halo effect across Prime Day, with approximately 29% more e-commerce revenue compared to an average June day. Smaller retailers, or those with less than $10 million in annual online revenue, also saw their online sales increase by about 21%, according to Adobe.
