What stores can I find a 4GB memory stick for my PSP?

May be...

I need a bigger memory stick for my psp and I just need to know what stores I can find them at. And about how much are they usually?

In the internet go to this link: http://www.us.playstation.com/PSP/Access…

don't buy sony's "official" memory stick, buy a normal one, their cheaper, i think the dsi uses the same one....

just go and get one that's the same shape as the psp one and don't pay any more than you have to.

What ever you do, DO NOT get one from gamestop. They charge you an average of $10 per gb.

I got a couple of 4gb off amazon.com for $17 each. I say try that!

DSI uses a normal SD card



Wal-Mart, Gamestop, or BestBuy all have them. but also almost anywhere that sells psp's

go to wal mart i got a 4gb there for $20
