A:AnswerStock is random and will depend on your local store because not every store stocks the same days. The best thing to do is check their website daily at random times to see if it's available. You could try contacting your local store to see if an employee knows when a new stock is coming in but it's unlikely they'll be able to give you an exact date.
A:AnswerI bought one back at the end of September. Your best bet is to check online every morning. I had to do that and was able to get one. Be patient! You will have a very hard time trying to get it in store. If you order on line you can have it shipped to your house or I believe you can choose to pick it up in store
A:AnswerYou can purchase games in store or in the game itself. While there are quite a few diffences between the two units the biggest difference between the full game and the lite imo is the ability to plug the full game into a television or monitor.
