Surely what of what one is paying for is "excusivity" (yes, it's a word, I didn't think it was, but I checked). One can generally trust a retailer to know precisely what they are selling, and pricing accordingly. If one diamond ring was only priced $500 more than another, it might not appear as shiny. But make the difference $5000, then people will go wow. I think some of the retailers have more fun selling things having exclusivity. Some people can surely justify Festool tools on their features, and some can probably justify them on other basis. I don't think sellers care why you buy. Just like anything. YMMV.
