Just been to M& S. Bought 3 special offers / meal deal thingies. 2 out of the 3 offers did not come up on the till- full price on my bill. Luckily i mentioned it to the lady on the till- 'did my 3 special offers come up?' She said only one had!! The manager was called and she said sorry about that. I would have expected a gesture of goodwill. Hope nobody else caught out by this. Check your receipts! I know M& S profits are down but they don't have to resort to this!!!
