If you can have it dropped off and picked up at an Amtrak Station, it's a great deal at around $80 boxed and shipped from any Amtrak in the US to any other Amtrak in the US. You roll the bike into a box that only really requires you to take off the pedals and rotate the handlebars around.
I had a mixte shipped from Colorado to California that way. I only had to put the pedals back on, and rotate/tighten the stem and the bike was back in riding condition.
