I buy games off this guy:

http://stores.ebay.com.au/CD-Bazaar

He has excellent prices and is very prompt with his shipments. All games are offical and the same as if you go and buy them at EB only at 1/4 of the price.

Often I am dumbfounded why people go to EB games and buy the $110 game when you can go online and get it for $30
