You may be better going for a higher interest rate credit card that are usually easier to obtain, as you will not be charged interest as long as you pay it off in full before interest is due....as per your intentions, that interest rate won't matter.
All credit cards carry purchase protection under the consumer credit act 1974 to reimburse for certain failed transactions or goods and services not being of satisfactory quality, not delivered etc also look for one that gives online fraud protection....therefore I would suggest you use the card comparison facility to the right side of this post.
Failing that it's difficult to advise which is the most appropriate card for your circumstances.
