Amazon offers downloads of Adobe Photoshop CS6 Extended Student & Teacher Edition for Mac, model no. 65171349, for $149. That's the lowest total price we could find by $61, although we saw a boxed copy for $24 less two weeks ago. These extended editions allows you to create 3D graphics, 2D designs, movies, and more.

Of note, you will be required to submit proof of eligibility to verify student/teacher status in order to install the software.
