[For Canadians]: 250 airmiles with hotel booking
 

The Canadian loyalty program Air Miles is running a promotion until the end of the month. If you book a room through them, you get an additional 250 airmiles. Their prices are run-of-the-mill, but for a cheap room this is a substantial discount. They even have some hostels, so you could stay almost for free.

Example: I booked a room in the US for CAD 116 (taxes in) and will receive 50+250=300 air miles. If you collect the cash version of air miles, this is a value of more than CAD 30.

Only 1 bonus per account.
