Any tips on sending a door from California to Michigan?

CudaChick has been using something called PirateShip (or something like that). Not sure how it works, but worth checking out.
I sold a set of KH disc brakes for an A body, spindles included and used Pirate Ship. USPS was $62 each for 2 boxes, 43 lbs. each and UPs was $60. I signed up for PirateShip.com for free and shipped them for $30 each, thru UPS. All I had to do was print the labels, tape em to the boxes and drop them off at UPS. You need to know the weight, length, width, depth of box to get a quote. I'll absolutely us them again.
