they didn't know why it was declined ,it just didn't work. the clerk then called the consumer hotline @ 1-888-388-2009 and was referred to this website. the card (coupon) was then returned to me with the receipt and i came home and got online. i'm a rookie on this computer, so please try to make this fix simple. i'm really not so sure it's worth the trouble anyway,because the first converter box i got doesn't work worth a darn anyway. it keeps freezing up and skipping all the time. i think i should stop watching tv altogether, there's not much on anyway.
