Question: About how much money would I get for selling these items?
I am planning on selling these items to gamestop: my Nintendo DS Lite, 6 Wii games which include ( High School Musical 3, Guitar Hero Aersomith, Cabela's Dangerous Hunts 2009, Prince Caspian, Daisy Fuentes Pilates, and Game Party), and two Wii guitar Hero guitars
Answer:
Gamestop doesn't give you very much for your items. I don't know how much exactly for these things, but they mark everything up when they sell it to the public. I would call your local gamestop, and ask how much they will give you for these things, and then ask how much they sell them for, and then list them on craigslist at a price that's in the middle, so you can get more money for your stuff, but you can write in the post that it's cheaper than buying them used at gamestop.
