GameStop.co.uk has reduced the price of both the Black and Aqua Blue systems to £134.97.
While most retailers have yet to reveal the extent of their discounts, Sainsbury's has posted adverts in national newspapers stating that it will sell the Nintendo 3DS at £139.99 from Friday.
Yesterday, retailer Walmart lowered the price of the system from $249.99 to $169.99 in the US.
Nintendo announced last month that the price of the Nintendo 3DS will drop by a third across the globe, a move that is unprecedented for the company so soon after a new hardware launch.
In addition to the 3DS price cut, Nintendo is giving 3DS early adopters ten NES and ten Game Boy and Game Boy Advance games free before other users.
To register for the Nintendo 3DS Ambassador Programme, users must simply connect their system to the Nintendo eShop before August 12.
Following the Nintendo 3DS price cut announcement, the firm lowered its fiscal forecast by 82% and saw a 12% drop in its stock prices.
