Bear with me here....it gets better.
I was surprised at the price of this ball because its good quality with a nice texture / feel to it and the finish is a nice quality metallic colour. A good buy at £5... but I then noticed a sticker on the ball which said there was a free Match magazine (Normally £2.99). We buy this mag anyway, so it was a ball for £2. The offer turned out to be redemption - you call a number:

So basically you end up with a cool football and 4 magazines for £6. (Saving £10.96) - or just the one for free, no questions asked.
