I just back from Office Depot and they have a new policy that says you can only use a credit card for the first $200 of a gift card purchase if you are trying to get the Blue Prepaid Amex card. So you could do $500, but the balance of the $300 needs to be cash. The one I'm talking about is the one that you then convert to the Permanent Prepaid. They have a sign up that went into effect today.

I can post a pic of the new sign if requested.
