Airmiles is offering 10x reward miles when you shop online until November 20th.

This offer can be used in conjunction with individual store Airmile offers to maximize your rewards.  Multiplier and any applicable store offers are based on 1 Airmile per $20 spent before taxes and shipping and do not multiply other offers.

Major exclusions are Netflix and Rogers but most stores are included.

If you still have the Airmiles toolbar, they are offering a bonus of up to 75 Airmiles for clicking through to stores through it rather than the link above.
