Open Question: I am African but can I get a US Prepaid Debit Card?

I know you all may think I'm crazy but I really do need this debit card. I can't seem to buy my musical instruments from stores in the USA because they wouldn't accept my country's Debit Card. My country doesn't use credit card so we do it the old fashioned way but it's not helping me in any way? Can anybody please (I'm begging) tell me where I can get prepaid debit cards for international users or anyone that can help me apply for one?
