Today i have ordered a Microsoft card digital and the $50.00 gift card code was sent to my email. I had a $100.00 gift card from Target. I checked my mail after 10 minutes and it finally had showed up so since i had another $50.00 on my Target gift card i had only planed to get only one $50.00 Microsoft gift cards since i didn't know what to do with it i thought mind as well buy another. So i went to Amazon and i went to buy and picked digital instead of mail since it was faster. Once i had clicked it, it had said error please see bank or something similar like that. I then thought that either the person that gave me the gift card gave me only $50.00 instead of a $100.00. So i went to Target gift card balance.com. I entered my gift card number and the 4 code on the back. I checked it and it said there were $50.00 left on the card. So then i went to Amazon again and i tried to purchase another since there was $50.00 left on the Target card, since i just checked. So i clicked order and boom, the same error code came up. So then i took a break off because taking a break of trying something for a long time and then coming back will actual make it easier because you don't have to think about it anymore. So i went back on after about three hours and i tried to do it again and boom, there it was ERROR. So then i decided to call Amazon support. I told them my situation and they simply said that they were just verifying because i had bought something earlier. They were just making sure that my account wasn't hacked or getting credit card fraud. So i discovered that i never knew that Amazon would be that protective over $100.00.
