I have used www.campustech.com to get software for myself and my college
aged son. They sell educational versions (often without the manual) which
are pretty much the full programs. I have gotten Illustrator very cheaply.
They have an Adobe promotion going on now for Illustrator, Photoshop,
InDesign, GoLive, Acrobat and LiveMotion for $379. All they require is a
faculty or student ID (pay stubs are fine).
