Well said. Beyond that, in the case of wire and connectors, I'm not about to go order wire from a catalog and pay same price I could pay for the wire at my local vendor... then pay shipping also.
Shipping on wire? Nope. Catalog price for wire right now after I drive ten miles, or catalog price plus shipping in a couple of days... why would I ever make the second choice?
