Love the retailer or hate it, but Twice has deemed Best Buy as the best national retailer for the fourth time. Over the last few years, Best Buy has expanded into new markets – Magnolia Home Theater & Apple products – while keeping its core business growing. Recently the retailer picked up Napster, started renovating it’s cell phone biz with upscale digs, and is even producing Best Buy exclusive products under the Blue Label brand. Over all, it’s hard to ignore how much Best Buy has evolved to meet new demands while retailers like Circuit City is taking its last breath.
