From Barbie to boxer shorts to Britney Spears, Dublin is cheaper than London but dearer than the US.
A British Consumer Association team visited nine European cities and Miami, Boston and New York in the United States, checking the prices of a luxury basket of branded Christmas goodies in cheap, middle-level and expensive stores.
They found the Secret Message Barbie doll costs, in Irish pounds, an average £8.03 in the US, £21.93 in London and £20.91 in Dublin.
The difference wasn't quite so marked for the A Bug's Life DVD, which cost an average £23.94 in Dublin, £26.17 in London and £14.27 in the US.
Britney Spears' Oops I Did It Again CD came in at £15.50 in Dublin, £18.54 in London and £9.88 in the US. The chic dresser may be interested to find a Ralph Lauren short-sleeved polo shirt would set him back £34.60 in the US, compared to £53.98 in Dublin and £65.47 in London.
And for those for whom fashion starts next to the skin, a pair of white boxer shorts by Calvin Klein costs an average £11.94 in the US, £18.55 in Dublin, jumping by more than £5 to £23.79 in London.
The basket also contained CK One eau de toilette, a Colour Gameboy and an Estee Lauder eye-shadow compact (blossom).
The whole basket would cost the consumer an average of £156.92 in the US, £248.24 in Dublin, £249.52 in continental Europe and £291.06 in London. European cities surveyed were Amsterdam, Berlin, Brussels, Dublin, London, Madrid, Paris, Rome and Stockholm.
The British Consumers' Association blames high UK and EU prices on the Trade Mark Directive, which "allows brand-owners to control the market and prevent their goods being sold at discount prices".
The association is calling on all EU governments to pressure the European Commission to change the Trade Mark Directive so traders can import cheaper branded goods from any country and retailers can undercut prices.
The Director of the Consumers' Association, Ms Sheila McKechnie, said: "This European law is a smokescreen for price-fixing as it is allowing brand-owners to charge consumers high prices in the UK and the rest of Europe".
