has anybody used an american express gift card to buy from here? it keeps saying error and i dont have a credit card. i want like to buy a nice bong :/
First make sure the card was activated and then make sure that you registered the card on their site to make it usable. I haven't ordered from GC but I had the same problem with an amazon order because i forgot to register the card.
More than likely the giftcard you have does not allow international purchases as previously mentioned. Thats also why you cant use giftcards to buy things off ebay. I would suggest just using a debit card.
Not all or even most gift cards can be used outside the US. Read the fine print on the back of the card.
