You need a Debit card that can be added to PayPal. The easiest solution that I know so far is to get a prepaid Visa Card from Botswana and signing up for PayPal using a Botswana address. Just make sure to add the correct Zimbabwean shipping address when making the actual purcachase on eBay. Whenever buying things from eBay just check to make sure that the item can be shipped internationally. If not then you can make use of an American address via a company like USAbox.com and have them reship the item to you.
