Staples offers Adobe Photoshop Lightroom 3 Student & Teacher Edition for Windows and Mac, model no. 65081059, for $64.99 with free shipping. That's the lowest total price we could find by $5 and the best deal we've seen on this software since Cyber Monday, when it hit $40 shipped. (Also note that Adobe Photoshop Lightroom 4 is due for release next week; yesterday we saw preorders of that version for $80 shipped, although it's since expired.) Sales tax is added where applicable. This software offers a variety of photo-editing tools.

Of note, you'll be required to submit proof of eligibility in order to unlock the software; click here for more information. (You'll be able to use the software in trial-mode for 30 days until you receive your serial number after providing the required proof.)
