Paying in the European PS Store has become easier.
Sony has simplified the process of paying for purchases in the PlayStation Store: the store now accepts cards from countries where PlayStation is not officially represented, such as Belarus, Kazakhstan, Georgia, Armenia, and others. Thus, paying for games and subscriptions in the Turkish or Polish PlayStation Store has become much easier.
There have been no official comments from Sony itself, so many assume that this may be a system error in the PlayStation Store that will soon be fixed. It is also not recommended to use your primary account for purchases, as Sony may take action against people who have taken advantage of the error for their own benefit.
It is important to note that Nintendo has long allowed purchases in the eShop to be paid for with cards from various regions.
