i would like to add something.
the most easy is to card flight tickets.
second id like to add is when you try to order with your
own debit or credit card in most times you can do it without problems.without even they contacting with you for verification.
so most important is if your ip isp is clean and with good history.
So what you can do is do few good transactions with your isp connection and with your device.
once your ip adress has good history then you are good.
coz this is the very important factor they analysing your connection.
Second issue is they often just give yoi error messages to trick you to make you think your information is wrong or ur cvv is bad.
amazon works exacly like this.
and also apple
