Call Of duty world at war xbox

So I am now online again with a new xbox 360 and I am trying to get hold of a copy of Call of Duty: World at war, nd trying to fight my Way round town with all the bargain hunters is a nightmare. They have actually got a sign on the shop door at game stating that due to the massive demand of shoppers for the shop that will only allow so many people into the shop at one time and there was a queue as long as the street. So stuff that if they think I’m queueing to get a simple game for an hour or so.

The problem I’m having is I keep bidding on eBay for the game but as I don’t want to pay over the odds and other people obviously want the game more than I do.

So do I stray across to amazon or do I persaveer and try and get someones unwanted Christmas present?
