Like I said, your seller seems to be rather generous with his 'handling' charge. $23 worth of generous. I can see charging a few bucks for the gas to get to the p.o., and maybe a couple more for fussing with customs forms, but gas and a steak dinner? Damn.
Suggested feedback: $10 item + $16 postage + $23 handling = WTF!! It could be posted as a positive if you feel so inclined.
Better luck next time.
