The Nintendo DS family—spanning the original DS, DS Lite, and DSi—maintained a manufacturer's suggested retail price of $129.99 throughout most of its lifespan. This wasn't accidental price fixing; it was a calculated business decision that helped the handheld dominate its generation.
Nintendo's strategy—hold the MSRP, bundle value, protect brand premium—paid off spectacularly: over 154 million units sold worldwide, making the DS the best-selling handheld of all time and the second-best-selling console overall.
