Right, as a UK tabloid I'm surprised they didn't mention that the UK has similar laws. If you are overcharged you can ask for a refund, and the store has to honour it:
In the 00s I worked for a supermarket that would always honour the price on the label if you pointed out an error (we'd then remove the label with the error).
We had teams that would regularly check all the labels to make sure they are not out of date. Nowadays many stores where I live now use e-paper displays that update automatically.
