In my view, A&L cashback card used to be a great card before they handed it over to MBNA administration. Don't use it any more. Switched to a better terms & reward cashback card from another provider.
Travel cards - forget them. Had one once and built up lots of travel points tied to a named travel provider. Then found it was better value to throw away the points and book the same holiday with another travel provider. Recommend go for cashback every time; you can spend cash anywhere.
