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
Ds light is $50, Dsi is $70 and Dsi Xl is $100
It doesn't cost anything if you trade your older version for it.
$80.00
About £110 Hope I helped
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
