Checkers/Food Lovers although Shoprite is cheapest, yet some Shoprites were good, other terrible. Depends on the branch and who manages it. I couldnt find BUTTER at the Durbanville Shoprite. Plenty of Margarine but no butter whatsoever.
Yes Woolworths is cheaper for flour, and occasionally sugar, but that's about where it stops. Look at meat and fresh produce and Food Lovers walks miles around Woolworths.
Checkers has been boosting its quality of items, I have noticed more and more imported from abroad items, mainly the US, and their range "Kitchen" is pretty good.
Pnp has brought out deluxe sauces etc, to compete, but you can barely find anything anymore. So its useless if you liked something, they discontinued it again immediately.
