Working out how much something costs in a sale is often tricky, as reductions are not always clear, but this year there is an additional difficulty. As given by retailers, the figures listed here are in Irish pounds. On January 1st, however, the euro will come into use. Even before then, prices will probably be given in both currencies, but be prepared for potential differences in rates.

One euro is worth approximately 79 pence; £1 is valued at €1.27. Working out what that means when dealing in larger sums may be awkward, but it also means you avoid the potential risk of paying more than you should. Most households recently have received calculators that convert prices, so taking one with you to the sales is one way to ensure you don't pay over the odds.

Remember, too, that despite the impression given in some outlets, items bought in the sales are subject to the same statutory controls that apply at any other time of the year. Your rights as a consumer are also unchanged. If you have any doubts about your purchase, keep all receipts and price tags, as these will be especially important when resolving any difficulties with retailers.
