My local GAME had some sale items including the full series of 'Passort to..' UMD titles for the PSP at just £1.98 each!!!!
It's an excellent bargain....but I'm not sure if the other stores have them at the same price. They are listed £9.99 on GAME's website.
I bought all 6.
Passport To Rome | Passport To Londond | Passport To Paris | Passport To Prague | Passport To Amsterdam | Passport To Barcelona
Apparently the Dudley branch of Asda has them for just 99p. It could be UK wide....let us know.
