The original Pokemon Yellow, Red, Blue, and Green versions are very difficult to find, as they are not made anymore and collectors offer insane amounts of money for it. The general range for a Gameboy Pokemon game in today's market would be around $15-50 if you can find a bargain.
Wrong. Used Pokemon games still range from $20-35. Even the old ruby and sapphire are listed at $29 as our store. The new Black and White are selling for $34, which comes to 36something with tax.
If you buy them online they're much cheaper, but you risk getting fake games or not even receiving the purchase.How much do pokemon games for gameboy and ds cost?
Well GameStop stops (yes, Game-STOPS) selling GBA Games after 4/1/11.

But used DS Pokemon Games - $29.99 I believe. That's how much I got a used Pearl for.

If you want Black or White, I suggest you bring $50+ or else you may not have enough.How much do pokemon games for gameboy and ds cost?
Well the newest game Black and White were only $35 in stores. So i would assume that the older games ( especially the ones for gameboy ) would be at an even lower price.
you wont find used black and whites at gamestop or probably anywhere. I bought my Black and White copies at best buy for $20 b/c they had a deal if you buy both you got it for 20 apiece

the used at gamestop will probably be 10 dollars
