Amazon.com Inc.’s Prime Day sale helped boost online spending across all retailers in the US by 30.3% to $24.1 billion, according to Adobe Inc., topping its estimate for 28.4% growth for the period ending July 11.

It’s a good sign for the online retailer as well as competitors such as Walmart Inc. and Target Corp., which hosted their own overlapping sales.
