I was going to use my voucher towards a camera, but in the end I didn't get a camera off amazon, I bought elsewhere. So I decided I fancied a waterproof mp3 player and found one exactly right on amazon.co.uk. Sorted my voucher out, but no. Had to buy off amazon.com. Dot com didn't have the mp3 player I wanted, so chose another - couldn't be shipped to England. Decided I'd download some music, but couldn't as I wasn't a US resident. Had a little chat online with Sangresh - couldn't change my USdollars to UKpounds, could only shop on Dot.com with them. Sorted!
I have bought CDs and am looking forward to receiving them in 6 weeks time.
Thank you AB22ET.
