I doubt that somehow. Go and check out some of the Portuguese places on the Kennington/Stockwell borders and I suspect you'd find cheaper staples like pasta, chorizo and general cakery than you would at the supermarkets. Our local deli sells most items cheaper than Sainsburies - much higher quality passata for less money (considerably less than the Taste the Difference version too), better veg, frozen seafood, high quality pasta, parma ham etc etc.
It always shocks me a little how much supermarkets think they can get away with outside of their core items and loss leaders. G'wan and have a look at how much Waitrose want to charge you for a few lychees in a prepackaged bag for example, or for many of the brands of spices you'd get far cheaper in your local asian store. .
I have tried - the Italian Deli by Kennington church is horrendously expensive. What portugese shops are there on the Stockwell/Kennington borders if you know the area better than me, cos I've never been in one? (Bar the all in one internet cafe/video shop/hairdressers opposite Kennington Park) Nevermind the fact I don't live on the Stockwell border!
I use East St Market for veg, Borough for meat and Lidl for other stuff, with Tesco quite often thrown in too.
