The following video is part of our "Motley Fool Conversations" series, in which consumer-goods editor/analyst Austin Smith discusses topics around the investing world. In today's edition, Austin discusses one of the biggest reasons Best Buy can't survive in its current form: a dated business model. Best Buy has historically sold you low-margin items like TVs and stereos as a segue to high-margin items like cables and accessories. This won't work in the modern age of retail. Overlay big red flags from management, and this is a business headed for the garbage heap without a fundamental business-model shift.
