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.
about $20 for all consoles
Honestly, you'll probably get about 2$.
Amazon trade in value is less than $5 and used games start at $7.50 today February 12 2012 though Gamestop wants $18
The 3DS is just given it's normal trade in value and way less than it will be sold for. Amazon would give up to a $88 gift card that you could use to buy a Vita Gamestop does not have a online quote of trade in value and then would charge state taxes for your balance owed on the Playstation Vita
Sadly, probably not as much as you originally payed for it. Gamestop's trade in value for the console is $18.00 (in perfect condition). You might as well keep the system.
Gamestop wants more for a used PSP than most other places or $100-120 depending on the model. Amazon wants $130 new for Gamestop's 120 dollar used model and also will purchase your games for trade in value. PS2 games do not trade in for the high prices that they were purchased for and at either location you may need a grocery bag of games to get your PSP
If you don't have one, they've got spares, but expect them to lower the trade-in value. The charger is an essential item rather than an accessory so they'll knock something off the value since they have to replace it themselves.
