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.

Bananas, roses and toys are some of the items hit by tariffs and price hikes could come as soon as late May, according to the retailer.

The retailer reported sales growth, especially in its e-commerce division, but also cautioned about economic uncertainty in the quarters ahead.
