(Reuters) - Shoppers spent about $14.2 billion online across retailers in the United States during the 48-hour Amazon Prime Day event, according to a report from Adobe Analytics on Thursday.

The Amazon ( AMZN ) sales event in July has also got retailers such as Walmart ( WMT ) and Target ( TGT ) launching deals to attract customers looking for steep discounts.

Adobe Analytics, which studies e-commerce transaction data, had forecast that consumers could spend $14 billion online across retailers over the two days, up 10.5% from a year earlier.
