Roughly 20-30 bucks, but it all depends on the quality of the game.
$34:99
$34.99 I saw this at gamestop and target that was the price
they give you $12.54.
Around £260 which is somewhere like $310?
Most gamestop's will only give you store credit and that depends on the condition and how old the game is in relation to its latest version
not much all that happens is cressilia becomes a running Pokemon
If you're talking about you trading it in for money, I can imagine they won't give any more than $20-$30.
Pokemon Diamond/Pearl are about 30-35$. Not sure how much they cost specifically at gamestop though.
$10
if he has played a Pokemon game before and beat it, give him platinum. Platinum is much harder then diamond or pearl. If he can't choose, ask him if he likes attack or defense. If he says attack, give him diamond. Diamond's legendary is offensive. Pearl's is very defensive. So if he says defense, give him pearl.
Gamestop no longer takes GameBoy Advances.
It depend if it is gamestop they will give 30 % of regular price
