If you're a fan of the TV show Community, you'll like this offer from Amazon.ca! Right now Season One and Season Two are each $16.99. If you buy them together, you'll meet the $25 threshold for free shipping.
If you haven't seen the show, it's worth checking out (at least in the opinion of this RedFlagDeals.com editor)! You can watch the first season on Netflix if you're not interested in buying the DVDs.
