Yes, this is part of the idea also. I almost was thinking of "credits". I had an idea similar to this before. Let me brainstorm more what you put there on there thread....
This idea was more so to allow people who are selling their bitcoins to place x amount into a credit card/voucher that they would receive instantly via email. Then they can spend it ( when the time is right) to buy bitcoins whenever they so choose via a credit card at anytime. This helps people get Bitcoins (again) quicker.
Sort of a pre-paid card dedicated to spending on Bitcoins at a later date.
Yes, I suppose that could be an option. Was trying to keep it strickly to buying Bitcoin but not a bad idea.
