Sears used to be a great place to go for auto service, but the rise of cheap tires and oil changes at places like WalMart really took a bite out of their business. They could have competed on price or quality of service, but I think they just gave up. The last time I was at a Sears auto center, it was a really grim deal. None of the employees seemed that interested in helping me, and their prices were ~30% higher than their competitors.
This strategy of embracing all things internet seems to be their current game plan: when you talk to a salesperson in-store, part of what they're trained to do is guide you through the process of shopping online. Clearly, this doesn't bode well for Sears' brick-and-mortar presence, nor for the employee forced to sacrifice his own commission, but it's where the future of retail is headed. However, to put all your eggs in the internet basket seems unwise. There's always going to be a market for skilled auto-mechanics that are associated with a company with a good reputation, but a Sears data center? I can think of dozens of companies that I'd turn to first.
