The news that Tesco accidentally offered iPads for sale at just £49.99 might come as a surprise - unless, it seems, you're a regular shopper.
In the past couple of years it turns out the supermarket has offered many products at better value than even its bosses expected.
From cheap Chocolate Oranges to cut-price beer, Tesco appears to have made a habit of the price-cut blunder.
This time around the supermarket said it would not honour the iPad deal, but it hasn't always been so lucky in the past.
