I ordered from them early in the year, and didn't hear anything for months. I sent multiple emails, tried calling, was going to dispute the cc charge when I didn't hear anything. In March, I got a reply from the owner of the website that he had an injury and resulting complications forced him to leave the website unattended for 4 months. He was working through the backlog, and had shipped my order. He offered to refund my money for the inconvenience, but I told him not to worry about it. My plugs arrived a couple days later, packaged well, everything was good.

I did get the impression he's a small (maybe even one-man?) shop, though, so if he had a sizeable backlog, he may still be playing catch-up. Or something else might have happened that put the website on the back burner. Still, I won't be ordering from there again.
