What a thread, being from Australia and relying on international purchases so much I would think that I am honour bound as the recipient as well. Would you not say to the vendor (if trusted & on this site I would) hey you lost something I lost something are you amicable to splitting the difference?
I have ordered several items from Whipped Dog and they arrived 3 - 4 weeks after purchase, an item from WM Newman took about the same time however everything there was just over $100.
It is still a pity that there are people out there working the system that is supposed to protect vendors and purchasers though.
