I have bought and sold a few sets that required shipping. I always used FedEx and if you know someone that has an account you can get highly reduced rates. Also, shipping to a business address will save you some money and keeping the weight below 50 lbs per package is key. You get an overweight charge if it exceeds 50 lbs. For packaging, I always left the tires on and put 2 layers of cardboard front and back. Then bagged them in trash bags and wrapped them in plastic. Best of luck with the sales and if I had air suspension on my S I'd be all over the BBS wheels.
