I would also submit the added benefit of having these items installed at the port is that they will all be covered by the factory warranty. It's worth considering. FWIW I had the exhaust and spoiler installed at the port and bought the caps, splitters and grills from forum sponsors at a considerable discount and installed myself.
Im getting all of the accessories for wholesale cost (installed)...so not sure how much better pricing I could find, unless I went aftermarket and had an indy shop install. I'd rather just have everything installed altogether -- saves me time and headaches; even if it costs me a little more.
