The chances of finding "gone off" food in Marks and Spencer is almost nil. They have someone going round checking just that. In all my years of shopping with them I have never, not ever, had that experience. With Aldi though it can be found fairly often, especially so called vacuum packs not being airtight. A subject brought up by another "genuine" reviewer a while back. You sacrifice quality for cheap prices with Aldi. Still, up to the individual isn't it. I heard about Tesco other stores also. Great eh. Will watch with interest. Goodbye Aldi? Hope so.
