This mainly aimed at the UK fans as I’m sure those in the US will be able to get it from you’re local record store…
If you don’t mind the wait then I believe the band will be bringing numerous copies of the EP back to the UK with them when they return after their US tour. You’ll save quite a bit on postage vs. importing from the US, and they’ll probably sell them cheaper than the stores anyway.
If you’d still like to import a copy, Amazon.com and TowerRecords.com will both be selling copies, Tower Records being the cheaper of the two to import from coming in at just under ?8 when postage is added.
Of course you can always go the technical route and download the digital single from various Warner endorsed online stores, though the only one listing it at the moment is Buy.com and they don’t actually have a price listed yet
