They only process the card requests twice a month, I think. Maybe something like the 1st and the 17th or something...can't remember exactly. After it is processessed you should receive an e-mail saying that you have the card ready in your account. Then you just go into your account and click on My cards...copy and paste the card # and go into your
amazon account and apply it to your account there. Then it will be waiting for you when you are ready to make a purchase. It is very easy.
I always make sure to mark the card as used as soon as I have applied it to Amazon, so I don't mistakenly try to use it again.
