My Best Buy purchase experiences have been fine. I like the simplicity of just going and buying off the shelf. And I've found their prices competative, especially if you wait for their sales prices. Their staff has seemed just fine to me also- reasonably helpful given the complexity of the subject and not at all pushy. I'd usually rather go there than deal with on line purchasing hassles like getting charged too much for shipping. Worrying about when UPS is going to arrive. Wondering what to do if my product prematurely fails.
