The cost to ship heavy items will vary, however one person on Reddit reported that UPS would charge them $720 to ship 300 lbs. And more specifically, another person on Reddit reported than an item almost 300 lbs (240) would cost $600 to ship a copying machine-like item from Texas to Tennessee, and that item would need to be palletized to ship. Once an item exceeds 70 lbs, then the shipping costs increase significantly.
