If you are in such a hurry to recieve your purchase is probably a good idea to let the seller know this at checkout and pay a bit extra for express delivery.
Then you will have your parcel quickly and the seller will know you are in a hurry for it and won't be so tardy getting the parcel out to you. Is only about $3 more and you will save yourself and seller unnecess a ry stress.
I waited 45 days for a parcel from China but did I leave bad feedback no I did not .
Because I know the harm it can do to a seller
Half the time sellers don't even see messages they get bombarded with more than they can read
