I was in a local Sony Style store the other day and was discussing prices and sets in the Sony line with a store manager. He told that for example the 52" Sony KDL-52W4100 that he was selling as well as other retailers like Best Buy and Circuit City is different than the same "W" series Sony that is sold by Costco, Sam's Club, and Wallmart. He said that Sony builds a special line that it sells to the warehouse clubs. I asked him what was different and he said they have the same panels but components in the Bravia engine are not as good and therefore the lower price. I have heard this talk for years from electronic retailers who won't honor their lowest price guarantees. They will tell you the set that is sold down the street is not the same. But that is the first time I heard it from someone who appeared to speak directy for Sony. I know for example the John Deere tractor sold at Lowes or Home Depot is not the same John Deere Tractor sold at a John Deere dealter. Webber does the same thing with it's grills. But in these cases you can clearly distinguish the differences in the products. So what's up with these Sony sets sold at the warehouse clubs?
