Are you sure these are reduced?

"Don't put your card in!" yelled the checkout girl, as she waved for some one - I assume, some kind of supervisor - to come over and remove the offending item.

Apparently there was some fault with the reduction system, and it was printing off the wrong barcodes. This item was supposed to 20p. Can't even remember what they were, probably some pastry or something. Some guy had nearly paid £300 for morning rolls.
