There aren't many places where I haven't shopped for food - Asda, Aldi, Morrisons, Sainsbury's, Lidl, Tesco, Iceland, you name it, I've been to them all.
One place I've never done a food shop is Marks and Spencer. There's always been something about the place that screams expensive, the kind of place your rich grandma would shop for her weekly joint of meat.
I don't have a rich grandma, but if I did, I imagine that's where she'd shop. So when I was asked to see how its products - and its prices - fared against budget retailer Aldi, I could have laughed out loud.
