This money has not been paid to AnthemShop.ca, rather your card company has put a hold on it for you while you check out. If your address information then fails to validate (maybe your shipping and billing addresses aren’t the same), then your payment will be declined. Your credit card company will release the Authorization between 2-7 business days after it is made depending on your bank.  Note that if you attempt to checkout multiple times, your card will be authorized multiple times.
