500px just announced a partnership with Adobe that lets users purchase the Adobe Creative Cloud Photography plan, which consists of Adobe Photoshop and Adobe Photoshop Lightroom, combined with 500px's Awesome account for the special price of $165 annually.
To do this previously would have required you to pay $9.99/month for the Creative Cloud account and $6.25/month for the 500px account. The new deal breaks out to a total of $13.75 a month for both, which if you were planning on doing the separate plans to begin with makes it a much better deal.
You can read more about the new arrangement at 500px.
