Hi, I placed an order on Alibaba, and the parcel supposedly left China on the 16th of September. The parcel is a Registered Air Mail, RJ846357229CN.
Should I be worried? It's taking longer than the estimated 7-15 days of arrival, especially since Singapore is close to China, it should not have taken this long.
In normal, there should be update showing it arrives in the US in another ten days. You'd better wait for more days to get update.
