Free Stuff Finder: Canada, and so far its proved to be very helpful in finding the latest freebies, coupons, contests, giveaways and more.
Its one of those websites that you add to your bookmarks and check it every now and again to see what's new and happening in the world of free stuff. Its updated quite frequently, at least a handful of new posts per week from what I've seen so far. They go as far as informing you of what the giveaway includes, how to access it, what you need in order to participate in it, any special info (like if you have to sign up to participate or if you can just go to the site and cash in) and even let you know when the promotion is out of stock or expired.
As far as being a hub for a collection of the latest freebies, its by far one of the better sites I've come across. Its easy to use, easy to read and easy to get to the freebies, contests, coupons and giveaways of your choice.
