For anyone who wants Season 5 on the cheap, Amazon.it have the Italian packaging version for just over 31 Euro. Postage is another 7 Euro. Total cost just over £32 at exchange rate of 1.16.
My Italian season 4 from Amazon.it came from the Amazon UK warehouse. Was a bit pissed that I'd paid nearly £6 for supposed postage from Italy. Still saved myself £9 on the UK version price.
