Is my credit card being charged?
No, but to be honest, we wish it would or at least fail to a point where we could see it in logs here - we cannot.
I was able to reproduce what you were seeing but what T-Man suggested in the other post, made mine work.
Perhaps another idea... If you have a smartphone, can you try the purchase on it and let us know what happens?
