the truth is that it may say 2 days, but it's probably not. If you use something like Priority Mail in the US which tag-teams off to the EMS service here in Ghana, it may arrive in Ghana within 2 days, but it takes FOREVER for the Ghana Post EMS office to alert you to the fact that a package is waiting.
At one point, I could track a package out of JFK and into Ghana within 2 days, but 3 weeks later I was still waiting for notification in my post office box. Even though the package also had a contact phone number (my husband's). I wound up going to the EMS office in Accra Central with the numbers from the customs form and having them track it there.
