Iceland is a false economy. Individual items may carry a low ticket price, but that isn't the same as saying they are good value. When you actually analyse what you are getting for you money in terms of the nutritional value of many (not all) of their offerings, it's could actually be considered very expensive. Adding in the cost to health of eating heavilly processed foods off balances the equation further. M&S isn't a whole lot better to be fair, but if you want value, then one can buy relatively low cost cuts of meat and plenty of cheap vegatables from many of the nearby independents and street markets. Iceland / M&S are both chains specialising primarilly in heavilly processed, pre-prepared foods. The latter has a mildly better quality offering, so I would prefer it personally, but it's all much of a muchness. To hold Iceland up as some kind of working class hero is silly though.
