I agree. We only shop at tesco because we have a tesco metro around the corner from us and a massive tesco extra in town selling everything and it's open 24/7 apart from 2200hrs sat to 1000hrs sun They even have guys going round washing your car while your shopping, at a £7 cost Well it is here in Swindon.
As for 'rip off' I'm not sure, they are running a business, if they can turn some people over who can't be bothered to compare then, who can you blame.
I'm happy with tesco and going by the profits in April this year, so is the rest
