Depending on the size of the object and location,I would highly recommend Greyhound buslines.
When UPS,FedEx& USPS tell me it is oversized and difficult and extra fees,blah blah blah..I call GreyHound.
If the sender lives near a GreyHound Depot,and you live near one too,it really is a great alternative.
Greyhound doesn't advertise as heavily as other companies,so it really is one of the best kept secrets when shipping a LARGE item.
I've had a Cowl hood,Chevelle doors,dashboard,a Bumper,gaspump as well as a 7 foot tall gas station island light post,all sent to me for near 1/3rd of what I was quoted from others,but it does take more time,average 10-15 days to reach you,depending on destination.
If there's room on the Bus belly coming near you,they'll do it,and yes insurance is available,but I've not needed it in the past,as I paid the sender well to reinforce the shipping container.Sometimes they have to ship it through intra connecting buses too,not solely one bus,so get the tracking no.
