Today only, Amazon.ca offers The Hobbit Trilogy on 3D Blu-ray / Blu-ray / Digital HD / DVD for $26.25 (C$36.99) plus $7.08 (C$9.98) for shipping. That's $5 under our mention from last month and the lowest total price we've seen. (It's the best deal now by $10.) This edition only includes all three movies, not the extras of the extended edition.
