I realise time is running short for you, but :
Many sites ask for cards, when there is a free introductory period but normally charges. One way to retain anonymity, or avoid passing sensitive credit card information over the ether is to use a prepaid card - W H Smith do a line of MasterCard ones, starting at £25. Once details given, and nothing charged, you can then spend anywhere that takes MasterCard. If they try to take any cash, the card will be empty. I have 58p left on one, a bit shamefaced about using it!
