First season of Charmed for 35USD???

Yesterday I found on a website a note that the first season of Charmed is now available in the USA and that there are also release dates for the UK and the Netherlands. I couldn't really find a date for the German (and Austrian ;-) ) market yet, but that's not really a problem for me.

What is a problem for me is first the date of the UK release (April 25th IIRC) and the price. On amazon.co.uk the DVD package costs 29.99pounds. On amazon.com the whole package costs only 34.99USD(!!!), so I'd save nearly 20€ if I order the first season in the USA...
