"A Credit/Debit card is required with all giftcard purchase. We will not charge your credit/debit card unless your purchase amount exceeds the value of gift card(s)."
So, Verizon requires a valid card to use a gift card. Okay. However, it charged my card $65 anyway , and apparently I now have a worthless $200 unusable gift card that cannot be redeemed online or in-store.
