Glad it's all worked out now, but I would have gladly shipped him a nice set if you would have just covered the shipping costs from here to his destination.
I don't see how someone could ship two separate boxes the same basic size/shape with the same contents and yet no red flags go off when the workers pick up one box and it weighs 60 lbs. and the other box is only 1 lbs.?!?! Especially the delivery driver, he has to carry the nearly identical boxes off his truck and to your house/business. The weight of each box is listed right on the label!
I mean wouldn't a dirty head be kind of hard to not notice half hanging out of the box or lying in a truck at the end of a run? A head isn't something that can hit the floor without making a serious noise, just roll under a desk/shelf/rack and become not noticed, or get accidentally kicked out of the way and be lost.
Did you see photos of the boxes as received by the buyer?
$500.00? What kind of magnum heads were these? I have a hard time getting $100.00 for a complete pair that I personally remove from great running vehicles!
P.S. If you happened to ship via UPS, they automatically insure each shipment for $100.00
