Just like Air Miles, Aeroplan is now offering an eStore where you can earn Aeroplan miles with every purchase. The store list isn't exactly the same, so check for your best deal and with which site. Remember also that Aeroplan miles expire if you don't use them, so you might be earning nothing if you can't use it in time.

I wonder where Aeroplan came up with this idea.... considering that they own Air Miles.
