No, this isn't a joke, I preordered mine just now and it works.

Step 1. Add the game to your cart
http://www.amazon.ca/Super-Mario-Galaxy/dp/B000FQ9QVI/ref=pd_bbs_sr_1/701-9366699-0637108?ie=UTF8&s=videogames&qid=1193986001&sr=8-1

Step 2. Add a filler item from this list
http://www.filleritem.com/ca.html

Step 3. Enter coupon code during checkout for $10 off, MAPOCTNCSAVE

I used VISA for checkout and the coupon shown as VISAPERKS, so, I don't know if it'll work with other credit cards.

Also, the cheapest item on the filler list is $1.25, so your balance should come out to $47.30 (14% TAX for me)

Edit: Remember to choose FREE SHIPPING! (You can buy other games using the same coupon code, too.) 

Interesting...I'm not gonna take a risk though...I wouldn't want it to ship late if I can go buy it at a store instead.

 Amen, praise be to Mario.

Wonder if I can start a cult =P 

^^
you definitely could, and people would join...haha

also a side note, all churches are tax exempt, so if you declare your house as your church or temple, think of the possibilities...

 sounds familiar :P. Ezekiel (Pulp Fiction) huh ^^

If only I had Mr Jackson's voice...if only...then I could pull off the cult...err church thing..yes I mean church...
