I still have my Target ad - it is 24.99 for Blu-Ray+DVD, 16.99 for DVD, and 29.99 for the 3-disc combo (not sure what the third disc is - maybe a digital copy?). There is an action figure for 7.49, and you save $5 when you buy both the movie and the action figure.
I generally find Target and Wal-mart to be the cheapest during release week.
