Shipping bigger car parts by air freight??

Greyhound would be the way to go for most shipping because they'll do COD, which is easier on everybody, plus they usually cost less than the traditional carriers. I personally find that Greyhound is faster and more efficient than FedEx, UPS, or DHL. The only major downside with Greyhound is that you can't do cross border shipping, which is a real bummer................
