Opinions on buying online. Of course, it is "better" to purchase from the local guy and support his brick and mortor operation as the money stays in the community. But when your on a tight budget, internet shopping can help a great deal. Is there actually a difference between the speakers bought at the local audio shop and bought online from places like accessories4less.com, audiophileliquidator.com, etc... just to name a few. Do the online and discount shops such as the above get "B-stock" or some other product that is not quite up to par, and the products that pass all inspections go to the local audio shops? Or are they identical in everyway? Obviously, you are giving up future service and relationship if you don't buy from the local shop. Thats a given. What are your thoughts and suggestions for buying from an online retailer for audio equipment?
