If your classes this Term have made you interested in paying Adobe to use their products, then now would be the time to subscribe. As part of their Black Friday Sale (which ends Friday, Nov. 24), you can get all Creative Cloud apps for $21/month on a one-year contract (there are penalties for cancelling early, as we describe on our help page on the topic, so just assume you’ll be paying the $262+tax). This is a savings of $5 per month.
If all you want are Photoshop and/or Lightroom, the regular Photography (20 GB) plan priced at $13/month for a year is a better bet. (They have tried to hide this option in favour of the $26/month plan with 1 TB of cloud storage, but click on the Compare Plans link and it will show up.)
