I'm sorry to hear that you got pulled into this scam. Unfortunately, the mules are often the ones who end up paying.
As to how the money can be returned--I think this is one of the areas that is surrounded by the most confusion. I know some people have thought they were safe, because they called their credit card company, asking if the transfer could be reversed, and were told "no." But - and this is where the problem lies - the credit card company is assuming that the account owner actually initiated the transfer, and has now changed his/her mind. But in this scam, the scammer would have used phished or hack accounts to make the transfers -the account owner had nothing to do with the transfer, and he/she did NOT agree to it. So the transfer was not authorized, and is not valid
When the account owner discovers the missing money, which can take a few days, even a week or two--it won't take too long to prove he/she was not behind the transfer, which will lead to the reversal.
I think this lady is part of int'l gang
This particular scam is often carried out by hackers in the former Soviet Union, and is used to generate cash (or in this case, merchandise, but the intent is the same) from accounts picked up in phishing sites or from virus-infected computers. It is not unusual for the major hacker gangs to have accomplices in the US and/or Canada. In most cases, a local accomplice who is aware he is committing fraud won't use his/her real name and information.
