no. an XL version is more expensive than a dsi. you have to trade it in for something of equal or greater value
$50.00
No, the DSi isn't the same in money value as the 3DS is.
You can trade it to gamestop for a discount off it, but it's not worth it, because the discount is smaller than the value of the dsi you trade in.
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.
no because of the value difference
it cost about 99.99
It doesn't cost anything if you trade your older version for it.
Ds light is $50, Dsi is $70 and Dsi Xl is $100
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
