Will you at any time implement these? I know that there are vouchers, and that there is a walk around it by making a product named "gift certificate" and make people pay for it and later send them an email with the voucher code. But it's clunky and also, if I am not right at the PC when they buy it people don't like to have delays like that. Especially when they're overseas and they buy while I'm sleeping they might have to wait for hours.
I wouldn't mind actually paying for an extension if you could make this possible.
