Be careful with such deals. Credit cards are charged on monthly subscription. Even though OP's service will be a one time payment, there is no guarantee he wouldn't generate a huge bill for the next billing cycle which may result in card getting charged the next month.Also the card details will be saved on the profile which I suppose can also be easy to unauthorised access.
I wouldn't recommend anyone doing this just for a couple of bucks.
great information and best suggestion.
yess agree, i think the same thing, OP can make and planning a crime, so do not be easily tempted if the account is connected and transacted by credit card if the account is transferred ownership. of course this will be difficult, be carefully and be a smart
