Best Buy will expand Apple Watch sales to all its stores in September, Fortune reports. The company started selling the watch in August and initially expected to have the watches in 300 of its stores by the holiday season. But in a call with Wall Street analysts, CEO Hubert Joly said Best Buy has seen such strong demand for the Apple Watch, both in stores and online, that sales will be expanding to all 1,050 of its storefronts next month. Joly also said 740 Best Buy locations are updating their Apple shop-in-shops to include new fixtures and more display tables for phones, computers and tablets. Best Buy will also begin selling AppleCare product service and support this quarter, with 50 stores acting as authorized service providers on a trial basis.
