Prepping for the upcoming March 27 launch of the 3DS, Target reminds Kotaku that they now accept DS, DS Lite, DSi and DSXL as trade-ins for store credit at some stores. Current values are: DS - $20, DS Lite - $30, DSi - $45, DSXL - $60. Not bad for essentially cash. But GameStop is running a better deal for 3DS credit right now.
