Hi! I need to purchase a couple of FI Q's subwoofers over the FI site, but as soon as I'm about to check out, an error that says " The card you entered cannot be used for this payment. Please enter a different credit or debit card number." kept on appearing. This apparently is the very same card that we use to purchase our groceries and other stuff. I did also tried calling my provider (Mastercard) and see if maybe I'm over my credit limit or if there is something wrong with my account, everything is fine. I also tried this process (please see link below) but still to no avail: http://www.soundsolutionsaudio.com/forum/topic/43085-how-do-i-pay-with-a-credit-card/ Please please!!! I really need to have these subwoofers. Scott or somebody or someone please help me! Thanks in advance!!!
