My favourite kind of mistake

Tautology warning: if redundant language offends you, look away now.

The issue here: ‘other’ and ‘more’.  Since comparison is implied by using the word ‘more’ you don’t need to specify that you are referring to ‘other’ cards (suggested re-write: ‘no loyalty card in the UK is more generous!’).  If you are really wedded to the inclusion of ‘other’, ‘more’ should be replaced with ‘as’.

I also take issue with ‘a great big 4 points’ since points are quantifiable as opposed to, say, a score of 4 points, where the score is singular thus in agreement with the hyperbole.

Grrrr.
