Be careful
Be especially careful with sale items since pricing errors are more frequent.
Remember that even if you don't see a price labelling and accuracy sign, the merchant can be required to compensate consumers if there is a price error at the cash register if he was exempted from the obligation of marking the unit product price. If you have to pay or paid a higher amount than the lowest price advertised for a product, demand that the merchant respect the price accuracy policy and compensate you immediately.
