Well, first off, welcome to the site.
I checked out their site, and apparently they're based in Illinois, you can contact the
Illinois Attorney General and file a complaint with them against The Parts Place. That should get your $200 back...unless they're looking for some trouble.
That sucks though...hopefully you can get it worked out, definately file a complaint, fill out the form on their site and mail it. I wouldn't send all those parts back though...I'm sure you ordered them for a reason!
