America’s largest retailer plans to raise prices later this month and early this summer, when tariff-affected merchandise hits its store shelves. Some prices already have increased.

Walmart, the world’s largest retailer, warned that is not immune from President Donald Trump’s tariffs. It plans to raise prices on some items as Trump’s global trade war sends the company’s costs higher.

NEW YORK (AP) — Walmart’s first quarter profit slipped and it said it must raise prices due to higher costs from tariffs implemented by President Donald Trump. The nation’s largest retailers posted strong quarterly sales Thursday and said it expects sales growth of 3.5% to 4.5% in the second quarter.
