I've had experiences where dealers decided I was probably going to just use them for demo and then buy on the internet. In every case they were wrong, but, maybe they are just tired of being burned and overly cautious? I AM very active on the internet - much more so than with dealers - but I never use a dealers time unless I am serious about buying from them.
In the mean time, the dealers that treated me this way lost opportunities for sales. Fair enough, that's their choice.
There was one particularly weird case where a local dealer sales rep confided in me that all of their staff treat me badly at that shop because once I borrowed gear from them for demo and then bought it used on the internet instead of buying from them. But I NEVER did that! Freakin weird. They went out of business fairly quickly, so maybe they were just in some kind of final upheavel....
