Normal Mail is not traceable. When customers make a purchase and selected normal mail, seller is not responsible for lost package and it also means that you cannot log non-receipt claim. If you really want to save a bit using normal mail delivery, take your own risk and responsibility in case thing goes wrong. Dont tell seller you have been using normal mail and nothing happen before. Accident do happen by chance. We don't want to waste time of disputing for this incident. Seller can only infom you of the posting date of normal mail and not able to check delivery status because it doesn't has tracking no. and untraceable at all.

Please take note lost mail do happen and quite often too. Hence we highly recommend you use store pick-up or registered mail.
