In the App Store for MAC, in the Top Free category, positions 4. 5. and 6. are Keynotes, Pages and Numbers apps, all at £13.99 each!! — FUNNY DEFINITION OF THE WORD FREE
Also note, they are the ONLY paid-for apps in the Top Free section. Now if it was just a random selection of apps, I would have put it down to a bug or oversight, but specifically 3 paid-for apple apps from the same suite of apps — something fishy going on.
