If your order is not successfully placed, you may see an error message saying something about an AVS Mismatch. What this probably means is that the billing address you entered on the order does not match the address on file with your credit card company. If this happens, re-enter your order and double-check to make sure your billing address is correct.
AVS stands for "Address Verification System" which is a security measure used by our website to create a more secure shopping environment online.
