Read All About It - Marketing Babble Murders English Language
I just heard an advert on the radio which ended with the phrase "now save up to more than 25% off". How many redundancies and/or plain logic errors can you spot in that?

Let's break it down.

now - do we really think they are going to be paying for a radio spot advertising for next summers sale, plus we were already told at the start of the ad that it was this weekend only (although you never heard that bit).

save - this is a pet peeve of mine, by buying something, even if it's reduced, you still aren't saving anything. Almost as bad as get item x free if you buy item y.

up to - means the top, therefore you cannot go over this.

more than - means the bottom, you cannot go lower than this.

25% off - reduced by a quarter - no problem with this as a stand alone statement.

So looking at the ad again you see that this weekend is now and you can make a saving by spending of a top and bottom figure of a quarter off. Now at this point "off" becomes an issue as I don't think you can save 25% off, you can get 25% off or you can save 25% - not both surely.

Anyway rant over - all systems back to normal (plus or minus 5% off).
