Scamming Flickr to Pay Flickr

Last week @mrayyan showed me a very neat trick. I was looking to upgrade my Flickr account to Pro, but when I tried to pay the $25 bucks on my credit card, Qatar was not on the list of countries in the form where you fill out the credit card info. Why that is so, God only knows but here is what I did to scam the payment system to pay Flickr.
In the option to select country I left it as United States, the state as New York and filled in a bogus ZIP code. In the rest of address fields I filled in my correct address which is associated with my Visa credit card. Filled in the rest of the info as normal and the card processed with out a warning.
The reason for it processing without any warnings is that Visa has settings for how stringently your credit card information gets checked which is set by the company accepting the payment.
Thanks for the tip @mrayyan.
