I think if I sat down and shared some of my experiences with you regarding B & M shops you would understand where I am coming from.
Believe me, I am not one of these sharpshooters who just loves to go in and make an *** out of a salesguy, in fact I despise those types. I go in hoping that the sales people know what they are talking about. But when it is obvious that they do not, and their displays do not work so that you can actually compare the products and their description of how they install the equip't is substandard, then why should I purchase from them?
The warranty is simply not enough. When you get into that you are just talking money -- and if the product costs twice as much as I can get it for online the question becomes do I want to pay double for the warranty. No, I would not buy an extended warranty that costs that much in realtion to the value of the product so I am certainly not gojng to "buy" the manufacturer's limiited warranty under those terms. It simply is not a strong enough selling point.
