I respectfully disagree, $300 is fair for shipping.
A 30 lb. 33x33x12 package insured for $2500 shipped fedex express saver is $280 from CA to TN. By the time you package the thing and drive it to the fedex store then you've earned that $20, easily. If you don't have the OEM box and have the store package it then you're out $50.
