Firstly what country are you in? That will make a difference... In the UK you can normally get a Wii on the day you want one! If it was a few months ago, that would have been a different story! There were Wii's (just with sports and nothing extra) being sold on e-bay for over £250! NOw they are going for the value in the shops. To be honest it is worth holding on to... Bu thave a look on e-bay and see what they are goining for by all means!
Got some great games comming out soon... Just have a look at the official site!
