If you already have a digital SLR, mainly a Canon T2i, T3i or newer T4i and are looking to invest in a spare battery, chances are you know how much a first-party offering from Canon can be. Right now, though, TheSource.ca has a decent deal on a Canon Accessory Kit which includes a bag and a battery for $69.99. Normally, this kit would cost you around $100, so getting it for $30 off isn't too bad -- especially if you plan on travelling with your digital SLR.

Though digital SLR batteries do last quite a bit, it's very risky to travel with only one battery. Turning the camera on and off, leaving it in stand-by and shooting in various modes can drain power pretty quickly and you never want to be left with a great camera but a dead battery. Sure, $70 might seem like a lot to put into a battery and a bag but, if you're going to buy these accessories anyway, might as well save a bundle in purchasing them together.

The deal is live now but quantities are limited. The promotional price ends on November 30. If for some reason the link above does not point you to the correct product page, you can find it by ending the code: 8005610.
