You can, though you might pay a bit for shipping, as they tend to come from aircraft graveyards, and often the cheapest shipping method is airfreight to your local hub airfield, as they are rather big, but internal airline shipping is capable of handling them without damage.
Have seen just how strong they are, saw an aircraft where it ran into a wall after the tow connection broke. New guy inside, and they forgot to disconnect nosewheel steering, there was no battery to run aux hydraulics (wouldn't have helped anyway, as there was no engine either, and half the pipes were capped with plastic plugs) so he only was able to put a few strokes in on the emergency pump before the plane hit the wall.
Not much damage to the wall, designed to survive pretty much anything short of a nuclear blast, other than a single hole where the tip of the radome crunched in. The pitot assembly in front took the initial impact, sheering off it's mountings and pushing back into the nose. Unfortunately right behind it is a large block, called " Assembly, electrical control", which contains every single electrical circuit, circuit breaker and relay for the aircraft in a single block, and the aluminium alloy tube sliced longitudinally through the central panel that makes up the heart of this box. Good thing there was no battery in, as these is no fuse between the main battery bus and this box, and the cable is rated to survive 8kA of current flow, while only rising 200C above ambient.
Luckily there was another airframe at the maintenance centre undergoing a full overhaul, as repair time on this box was estimated at 2 years plus. So, undo 6 bolts, remove 200 electrical connectors, a few dozen hydraulic hoses, the remains of the pitot static system, airconditioning and oxygen systems and nose off, on a pallet and fly away, with the new to the plane serviced nose arriving the next week to be installed.
Radome popped up by the shop next door for service and inspection, and aside from scratches from the steel wall, and needing the stainless steel tip filed round again, it survived unscathed with no delaminations in the resin composite. Cleaned up, painted and tested, and back into stores it went.
