With just 34 days to go until the euro notes and coins are introduced, the January sales will mark the first time many shoppers will have given serious thought to the currency.
Consumer affairs organisations have spent the last year promoting the worthy message that early preparation would ensure a smooth transition from punt to euro. For most of us, it's too late for that now.
The appearance of dual pricing on receipts and menus - an amusing novelty at first - was soon largely ignored by many consumers. But with E-day fast approaching, it's time to pay attention.
As one inspector from the Office of the Director of Consumer Affairs tells the people he meets while promoting the euro around the country: "It'll be a bit like going on holiday but not coming back."
The Consumers' Association of Ireland's chief executive, Mr Dermott Jewell, said retailers and service providers should be careful of scaremongering about the euro.
"Customers are well capable of dealing with the changeover. This should be a very, very simple process but in a number of areas it's simply not happening that way," he said. In some cases, the changeover was being used as a "sad excuse" to raise prices.
Mr Jewell said one patron of a Dublin city-centre pub contacted the Consumers' Association when he noticed that an average of 6p had been added to the price of most drinks. This would "make things handier" for the changeover to the euro, he was told.
Service providers and retailers can be investigated and "named and shamed" but ultimately the power to stop unfair practices lies with the customer, said Mr Jewell.
"It's the consumer who is going to decide whether or not they want to give their business to that type of trading."
Ms Pauline Mulligan, euro information officer with the Office of the Director of Consumer Affairs, said there was plenty of "anecdotal" evidence that prices were being raised in advance of the euro becoming legal tender in the State.
People were particularly concerned that typical supermarket prices such as £1.99, £2.99, and so on would be rounded up.
She said large retailers such as Dunnes Stores had told her such price tags had been phased out in recent years.
She said the Office of Consumer Affairs approved of the "rounding" up or down of converted prices to two decimal places but not of "smoothing" prices to an unequal amount.
The New Year was a popular time for retailers and service providers to up their prices and the introduction of the euro was not necessarily to blame, she said.
"People are ringing saying the price of x, y and z is going up. What we're saying is that prices will go up and that won't change with the euro coming in."
Ms Mulligan said she welcomed a by-product of the changeover - the fact that consumers had become increasingly aware of prices.
The Office of the Director of Consumer Affairs will investigate any situation where a consumer spots a discrepancy in price conversion. This will be the case whether or not the business in question is signed up to the voluntary national code.
However, Ms Mulligan advised consumers to point out any discrepancies when and where they spot them.
She mentioned the recently published survey which found that 96 per cent of dual pricing in the State was correct.
Incorrect pricing was often a result of a genuine mistake, she said.
One retailer had multiplied his prices by 1.27 rather than dividing by 0.787564. Others had divided by 0.79.
"They're reasonable mistakes to make. It's not completely off the wall. We didn't find any cases where there was a blatant attempt to rip people off."
Ms Mulligan said the survey had found that the majority of staff had a working knowledge of the euro and would be well equipped to handle queries and complaints.
On a seasonal note, if you're planning to take the family to a performance of the Christmas pantomime, Sleeping Beauty, in Cork Opera House next month, you will be asked to part with some rather unwieldy amounts of money for your tickets.
Prices are £9.06, £10.24, £11.81 and £13.39. After the New Year, of course, these prices will convert into the more manageable €11.50, €13, €15 and €17. Last year's prices for performances of Cinderella cost £8 - £10.
