Ds light is $50, Dsi is $70 and Dsi Xl is $100
$50.00
You can trade in a DSi for money off a 3DS yes. Be warned that the trade in price for a DSi is at rock bottom pretty much.
it cost about 99.99
no they don't let you trade in concles yes, you can give them your ds light for like 100$ off a dsi
200 bucks
It doesn't cost anything if you trade your older version for it.
i got a black dsi and i like but if you are thinking about buying a dsi wait till the ds 3d comes out because that is much better.
At Gamestop if you trade your DSi for a DSi XL you get $80 off the DSi purchase($189.99). If you trade your DS Lite for a DSi XL
$80.00
About £110 Hope I helped
I don't think a TV. is worth as much as a flea market AND a DSI
