But I don't advertise it.
I offer friends the option to pay in part or in full via online gift card which they can pay for by CC

The only problem with credit cards is that there have been several instances where providers accepted a credit card, and then the hobbyist had the nerve to call the credit card company later to dispute the charge and have it reversed  So just a side note to ladies, if you do use them, please only use them with those you trust!

My two cents, I don't want to pay providers with Cards. For multiple reasons but the main being that it's traceable. Providers that don't accept Cards is mainly from the charge back possibility, which I personally understand but a lot of guys abuse this. I know one lady that will accept cards but only from people they have saw for a while and can trust. I just personally choose not to use them.
