But that's an import!![]()
Which doesn't really matter in the PSP's case as it is region free and the power supply is multi voltage. The only issue would be warranty. However in this case obviously including shipping it would most likely cost more then buying one in the UK. Having said that if it wasn't being released here for a while and someone wanted one right now it may make sense for them.
As far as I am aware the Argos deal of £129.99 including a game priced £19.99 or less and an accessories pack is currently the best deal.
