Very late contribution, but I think I can explain (not excuse) this. The Oregon address is for a reshipping service that sends purchases to Singapore. Import tax is automatically included once the buyer declares the value of the purchase. This buyer was probably hoping that if you sent the bag direct to Singapore, she could avoid the 7 per cent tax.Had this one daitai211 simply not pay for a bag after asking me if I would ship to Singapore. I said I would if she paid for the shipping but it would be free if I were to ship to her verified address in Oregon. After that, I never heard from her again. 100% positive feedback I guess doesn't seem to mean much anymore!
