First try and get them to change it by asking for a feedback revision and state to them the postage cost was

x amount and the cost to deliver it was x amount for a nett loss of x amount.

Explain they had to travel for 1.5 hours to get it to them as they thought it may get broken in the mail and it cost

them a lot more than the postage cost to deliver it,(so they were in no way ripped off).

If they wont do that then just state: Hand delivery cost was x amount,x amount more than postage cost,(then add

their user ID so that everyone that sees that comment can block them).
