Disclaimer: shop.ca is notoriously overpriced but you can find some deals hidden amongst the crap.
TD is offering a $50 credit if you use your aeroplan visa, no minimum purchase, plus 3,000 aeroplan points. If you've got something coming up that you'll need to buy (that is around that price and not a total rip off) it could be worth checking out. It looks like the code expires dec 31 so it could be handy for Xmas presents, if you're into that.
