RedFlagDeals stumbled upon a listing on Canadian retailer Future Shop for a two-toned, Crimson and Black Nintendo DS Lite bundled with a matching carrying case and Brain Age 2. The entire set was priced at $159.99 Canadian dollars (approx. US $153). It was to ship on August 20 alongside the brain trainer's release date.
Unfortunately, the listing has since gone missing. We really dig the new colors and the deal. Here's hoping it comes back up close to Brain Age 2's launch, either on Future Shop or another retailer site.
Update: Though it hasn't returned to Future Shop yet, Gamestop has a listing for the bundle, priced at $149.99, with no image available and no mention of a bonus carrying case.
