shipping a manifold

Any suggestion as to how to ship a cast iron intake manifold as cheaply as possible???
use a 3rd party shipper: parcel monkey, shipping easy, etx

signup is free, rates are well below UPS site and in-store. box it, measure it, weigh it, print the label at home and stick it on there and drop it off with a driver or at the local.

i sent a 45lb box LA to houston this week and it was bigger than how i would package a manifold and it was only $27

pro-tip: don't fudge the numbers at all and if anything round up that 1/2" and that 1/2 lb. also, if you can reuse standard sized (read: amazon) boxes the calculations fall more favorably.

the only down side is that they only offer standard insurance. so if you need any more than basic service you're SOL.
