Put simply: if the price ends in 1,2,6,7 you round down (to nearest 5c). If it ends in 3,4,8,9 you round up to the nearest 5c). €9.99, becomes €10 for example and you won't be given any change. €9.96 becomes €9.95 and you'll not pay the extra 1c. This all only applies to cash transactions from tomorrow onwards. It's all voluntary but we think its a good idea.
Got it ? Great!
