Adobe offers downloads of its Adobe Creative Suite CS5.5 Production Premium For Windows or Mac (pictured) for $1,699. Coupon code "SWITCH" drops it to $849.50. That's the lowest total price we could find by $447. This software suite includes Adobe Premiere Pro CS5.5, After Effects CS5.5, Photoshop CS5 Extended, Adobe Audition CS5.5, Flash Catalyst CS5.5, Flash Professional CS5.5, Illustrator CS5, Adobe OnLocation CS5, Encore CS5, Device Central CS5.5, Bridge CS5, and Media Encoder CS5.5. Coupon expires September 30.

Also available are downloads of Adobe Premiere Pro CS5.5 for Windows or Mac for $399.50 after the above coupon. That's a price low by $245.

Of note, this deal is purported to be for users who migrate from Final Cut Pro or Avid Media only; however, there does not seem to be a stage at which you'd need to validate that to get this price.
