I shipped a bike(minus wheels) from one coast to the other a couple weeks ago.

A local bike shop sold me a bike box(included all of the pipe foam wrap and foam blocks for dropouts) for $5. That was a well spent five bucks. I also opened a personal account with Fedex(no cost to start one),which saved about $18 in shipping.

The total was $51 and change. without opening a fedex account, I was quoted $68. Time frame was 7 days, coast to coast.

BTW, the package weight was 24 pounds, and size(41x29x8)

I should note: I did go to one of the local mail box joints first. I was quote $84 to ship via fedex from them, and $104 via USPS. I got an education and saved money going directly to a Fedex location.
