An accidental sale caused by the Croatian PSN staff have allowed some people to save a lot of money.
How much people actually saved is quite remarkable. While a new copy of Hitman: Absolution and Sleeping Dogs would usually cost around $80, this sale meant that people were picking them up for a far more likable 80KN. This translates roughly into $13. Obviously, this lead to far greater numbers of the games being sold, with people creating and selling brand new PSN accounts and then selling them later.
The Croatian PSN staff have responded by disabling the purchase of PSN funds which would stop people from buying so many copies. The problem has now been fixed, and everything has returned to normal. Shame.
