Sainsburys at London Colney started life as Savacentre, the JV between BHS and Sainsburys back in 1990. In 2005 the hypermarket was split in two and became home to today’s Sainsburys and Marks and Spencer. The store is roomy, around 25% is given over to non foods and service counters from deli and butchery to cheese and fish run along the back wall. Sainsburys is a very solid food retailer that does most things pretty well. However, there are very few surprises. It is all quite safe and a little antiseptic. In the emerging grocery market where everyone is going to run much faster, is this enough? A genuine price war (as opposed to the phony one we have now) would certainly put pressure on Sainsbury’s margins.
