Second time in three weeks I have noticed an overcharge at the checkout, this morning it was sugar, ticket price 70p checkout £1.09, the other week it was apples overcharged by 50p. They used to give you back double the difference but not anymore so I presume it is a common occurrence now probably due to less staff. When I see shoppers with full trolleys I wonder if they ever check prices and imagine Tesco and probably other supermarkets do quite well out of these mistakes before someone brings it to their attention.
