Best Buy, the world’s largest electronics chain, announced it plans to offer the Apple Watch in 900 stores come September 4, and expand availability to all of the company’s 1,047 big box stores in the U.S. by the end of the month. “The chain began offering the watch — offering models for between $349 and $700 — less than three weeks ago on its website and at 100 locations,” explains Bloomberg. “It has performed so well that, together with Apple, we’ve decided to roll it out,” said Best Buy CEO Hubert Joly. How the device sells through the retailer could help Apple decide whether the wearable will become a mainstay in its lineup.
