Consumer-electronics retailer Best Buy has taken a stab at estimating how much tariffs could hit sales. If the 10% tariffs on China that began in February remain in place all year, that could cut 1 percentage point from comparable sales growth, the company said on its earnings call. That will hurt: Without any tariffs, Best Buy had expected this measure of sales to be somewhere between flat and 2% up in the financial year ending in early 2026.
