Well, this is unexpected, buying a battery online.
There is a reason behind this though!
In Edmonton: 16CAD+
Woah, in Hong Kong I could probably get this in a shop for around 40HKD (~6CAD). EBay to the rescue!
EBay: 4CAD + free shipping
I was in a slight hurry as I just received a Canon EOS 650 camera as a birthday gift and I couldn’t wait to get it up and running. So I went with a Canada based seller which raised the price to 10CAD and gave me a shipping time of a week.
Overall, it’s a battery, it’s from Panasonic, it works.
