Just like the price to purchase a used game depends on the game so does thr trade in value, although is will be less than half the selling price
depends where and how much the games are worth.. (older the games less money they are worth)
No...
Game stop
No of course not, maybe for a PS3 game, but not the latest releases
No a Nintendo Wii trade in value is way less than the cost of a PS3 and you would have to pay the extra money. Much better just ordering a new Black Ops PS3 for amazon and getting the $50 future amazon item discount and the free game and download
Yes, but you will need to pay extra.
People will game share with you. Some people will also trade there PS3.
you can sell a Ps3 40GB for atleast £135 In the USA that would be at the most and in dollars, getting more than $100 would only be in trade
Depends on the game and how new and popular it is. More than likely the games you want to purchase after trade in are the same ones they want to buy.
If your looking for the difference if you trade in your wii it would be about a 100$ to 300$ depending on ps3 model or bundle. I hope I helped.
No, you will definitely cause no harm to the game if you spend too much on the internet on the PS3.
No. This is not possible to do. Unless they both have the same value.
