U.S. retail sales increased solidly in July, supported by strong demand for motor vehicles as well as promotions by Amazon.com and Walmart, though a softening labor market and higher goods prices could curb consumer spending growth in the third quarter.

Retail sales rose a solid 0.5% last month from the previous month, and June spending was stronger than expected, according to the Commerce Department’s report released Friday. June’s retail sales were revised upward to 0.9% from the original 0.6% increase, the agency said. The pace in July matched economists’ estimates.

U.S. retail sales increased as expected in July as consumers hit automobile lots and took advantage of online sales.
