When you place an order, we obtain an "authorization" from your credit card company or PayPal. This merely confirms that the funds necessary to pay for the order are available. We do not actually collect your payment until your order has shipped. More likely than not, you're seeing this initial authorization as well as the actual payment if your order has recently shipped. Neither PayPal nor most credit card companies do a very good job displaying/explaining these different types of transactions when you're viewing your account online. Rest assured that the temporary authorizations with soon disappear. If you are still concerned that you may have been double-charged after at least one business day, then we encourage you to contact your credit card company or PayPal to confirm that, in fact, a duplicate transaction has occurred. In the unlikely event that this has happened, contact us with your order # and we will investigate and resolve the issue.
