I hope someone can help me. I'm planning to start an online store buying, selling, and trading video games, DVDs, and computer games. Do anyone know of just one supplier that may deal with all of the abovementioned items? I'm not looking for closeout items, but mainstream new releases that you will find in your local Best Buy, Circuit City, or Wal-Mart Stores. Thank you very much.

Your problem will not be in finding one, but one that will sell you the stuff at a good enough wholesale price that you can make some money.

If I were going this route, I would Google for
wholesale AND nintendo OR xbox OR playstation

I'm betting most of the hits will include vendors who deal with them all... and along the way you'll probably find ones that also deal with a wider range of stuff like DVDs and software.

I hope this helps!
