HMV will stock Nintendo's new 3DS XL handheld at £179.99, the retailer has told CVG.
The RRP is the first issued from a major UK games retailer, and could be repeated by other outlets such as GAME and GameStation.
Nintendo does not set hardware RRPs in Europe, with retailers using the trade price and international RRPs as a guide.
But with the new enlarged handheld priced at $199 in the US, there has been a varied response in the UK.
ShopTo and Play.com have both gone for £179.99, though had cited an RRP of £199.99. Zavvi, meanwhile, is selling the device at about £210, expecting the RRP to come in at £249.99.
Superstores are not yet responding to the new console. A spokesperson for Tesco told CVG that it is "too early" to list the handheld.
The 3DS XL will launch in Europe and Japan on July 28th, weeks before it hits retail in the US.
North America retailers, which will begin selling the new handheld from August 19th, have been set a $199.99 RRP.
The 3DS LL will sell in Japan for about 18,900 ($235).
On current exchange rates, £179.99 is about $280.
Nintendo says its new handheld boasts a 4.88 inch top screen, a 4.18 inch bottom touch-screen and in some regions comes with a 4GB SD card.
