Holy crap! That is what I feared, a bubble envelope.
Should have been sent in a box, to many horror stories of cared figures sent in an envelope. I have see the results on vintage SW figures and it's not pretty.
Registered air mail with signature, it may have cost that much. Sometimes the label is the cost but being registered & with signature would be above that and not show on the postage label.
Even without insurance, it's still his own damn fault IMHO that it got damaged sending it like that. Hopefully Paypal will come thru.
