Regular Mail Rules
The Regular Mail shipping method does NOT have a tracking code. This shipping method is the most simple form of shipping. It can not be tracked and in case of lost mail it will never return to us.
For above reasons, regular mail is the cheapest shipping method. Since it can not be tracked, we can never know if the package has arrived to you or not. Due to this reason, an order shipped with Regular Mail can never be reshipped.
Regular Mail has NO tracking and NO reship rights.
