Yes, great point. My warehouse has pretty "reasonable" shipping rates with UPS, but I don't think I, nor many dealers, could afford to ship a Kapex (65 lb.and OVERSIZE box) overnight across the country, charge $4.00 shipping and not lose $$ (or make it so close to losing $$, that you'd wouldn't do it). Amazon, because of its' size and the soooooooooo many other items it sells, can afford these types and scales of "loss leaders". There are a number of dealers (myself included) who have totally free shipping on all Festool sales - no minimum size order. In a real way, on a small order, that is a "loss leader" that we offer as a way of being "competitive" and/or thanking a customer for doing business with us. But, the Kapex overnight example is something I could never match.
So how does this different from the Ebay business of the 'microsoft money'? Money saved is money saved. Getting it cheaper is still getting it cheaper. The methodology is merely semantics.
In defense of Real dealers: I see this as a rule being bent here and it is not in your favor . $4 overnight shipping is a financial incentive being offered to the end user, same as the Ebay thing[2cents]
