sure. T078 is ok.
Would you like to do meet up or mail the item back then I post the new item to you?
But you need to pay the postage fee from your side, because Gmarket charge commission on postage you know (SingPost postage fee is fixed). I do have loss when doing postage.
The difference will be accumulated on your next purchase. Once hit SGD166, you will get 10% off permanently (as member price).
Please mail it fast if you choose postage cos I'm going overseas at the end of the month.
