Nintendo is reducing the price of the DSi and the DSi XL, the company announced on Monday.

Starting on September 12, the Nintendo DSi will retail for $149.99, down from its current $169.99 price tag. Nintendo is also reducing the price of its DSi XL from $189.99 to $169.99 on the same day. The Nintendo DS Lite's price will remain at $129.99.

Although Nintendo says it's reducing the DSi's price to give consumers more "value," its decision could be due to declining sales of the handheld. In June, the company sold 510,000 DS units, according to NPD. Last month, it sold 398,000 units.
