The most effective way of ensuring the changeover to the euro does not lead to an increase in prices is to empower consumers to be vigilant in monitoring prices. This is the objective of dual display of prices. Dual display helps consumers to familiarise themselves with the new currency and enables them to build up a scale of values in euros so that they can be confident in making purchases in the new currency. The key initiative to encourage dual display of prices has been the development of the national code on euro changeover.
The Director of Consumer Affairs has contacted over 200 trade associations, inviting them to sign up to the national code on behalf of their members, or to draw up a sectoral code of their own and seek her approval for it. To date, a total of 11 trade associations and 17 individual companies have signed up to the code. The director's office is in the process of responding to applications from close on 100 further potential subscribers to the code by individual companies. The director has approved four sectoral codes submitted to her by IBEC-EAN – subscribers include all of the major supermarkets and retail chains – the Irish Petroleum Industry Association, Clé and Booksellers Association, and the Irish Insurance Federation. A further two proposed sectoral codes are currently at an advanced stage of examination by the director's office.
