Select Walmart stores offering $100 credit toward 3DS with old DS trade-in

This Sunday, the 3DS launches in the US and, to celebrate the occasion, US-based megastore Walmart is offering quite the deal for anyone who lives in one of a dozen states. When purchasing the new handheld, consumers in Alabama, Arkansas, Florida, Georgia, Kentucky, Missouri, Mississippi, Oklahoma, North Carolina, Tennessee, Texas and South Carolina will have the option of trading in their used DS for a $100 credit towards their 3DS purchase. If they've got two old DS systems laying around, both can be traded in for $200 towards a 3DS, but that's as high as Walmart's willing to go.

The trade-in program will start this Sunday with the 3DS launch and continue through April 30. This promotion is in-store only -- sorry, no online orders.
