Another long-time satisfied Crutchfield customer. Sure, they're not always the lowest price, but the lowest price is not always the best value.
I bought a D3 from them a couple weeks ago. I wanted to buy an extra pin for the free adapater harness that they include so that I could hook up the VSS without a wire tap in my 2006 civic. I called their customer service and they sent me an entire new adapter harness free, so I ended up with plenty of extra pins.
Plenty of other examples over the past 8 or so years that I've bought from them, but I'm starting to sound like a Crutchfield
