I'll just share my experience.
After seeing the first post today about the double charging, I checked my account, & found the same thing. I was charged about 2 PM yesterday, at the exact same time I got my order confirming email. This morning, about 9AM, I had an email stating that my payment had been processed. That was the same time the second charge showed up. On my online statement, there was a contact number, so I called & got an immediate answer. No recordings, no automated prompts, nothing. Just a real, live guy.
When I explained my concern, I was assured that the first charge would drop off at shipment. He said that the first charge was basically a test to check the validity of the form of payment. I told him that according to my statement, there was no 'hold' on my account, just 2 completed withdrawals. He said that some institutions did this as a precaution, but that the $66.98 would be refunded at shipment.
I was also told that they were waiting on a delivery truck to arrive, & that shipping should commense by Monday. If after my shipping confirmation email, the separate charges remained, I could call again & they would take care of it.
I'm OK with it for right now, but I hope this was just to get the subscription started. I really don't want to have to check behind them every month for the next 2 years.
