Marketing lunacy

Today, I had to get a prescription filled at Boots. So I treated myself to a sandwich and some apple juice for breakfast - gotta have some upsides, right? Anyway, the nice lady on the checkout informed me that I could get them cheaper under the meal deal if I picked out a yoghurt or some crisps or some fruit or something. So I ended up with a small plastic packet of 'Shapers Crunchy Apple And Juicy Grapes' for the remarkable price of -45p (RRP 70p). I'm suspicious of any product that contains pre-sliced apples, as they must be packaged in an inert atmosphere to stop them going brown, but hey, it's only 46 calories, and, according to the packet, 'DETOX FRIENDLY!' Bonus.
