Totally got this idea off my good mate Saint. There are a bunch of games coming out around this time of year and when there is a game I want, I always pre-order.
Things is not every store will offer the pre-order at the same time, which means you can either wait, periodtically checking them till all the retailers are offering you that game for pre-order, or you could just pre-order the game at a place that will price match for you later! No fuss~
The benefit to this is you can put in your pre-order, go away and no need to worry about remembering to pick up the game. Eventually when the date nears, the company will give you a call telling you to come collect the game. At which time ALL the stores will finally have their prices out. Pick the cheapest price, and get your retailer to price match for you 
That way you don’t need to worry about missing out on the best price, yet you’ll be secure knowing you will get a copy of the game!
And the difference can be huge, I remember price matching StarCraft 2 down to almost $70AU, when the place I originally ordered from was charging close to $100AU. Crazy, I know!
Image cause Rock Band 3 and Cata are my two key games this summer ;D
Wish I’d done that, paid the full price for my copy of SC2. Then again, figure it makes up for previous youthful indiscretions with Blizzard products ;P
Ahaha…. *nervous twitch*
