If economic inspectors discover too many mistakes between the price charged on the bill and the price advertised in supermarket racks, stores will risk a fine.
An official warning will be issued if one percent of prices charged differs from the price advertised in the shop. Storeowners will be required to seek an amicable settlement and pay up if mistakes in pricing range between one and ten percent of items.
Supermarket chains will have to fork out 1,000 euros. For smaller stores the fine is 500 euros.
Belgium's Economy Ministry claims that on average between 4% and 5% of the prices charged are wrong.
