where can I buy Photoshop? CS6 too expensive.

I know this was posted over a year ago, but your question still says "unanswered". So, I figured I would share my input. The best option by far is to purchase the "Photography Plan" from Adobe. and the reason is because it is so easy to afford. Hear me out. The plan costs $10.00 a month. That is ludicrously easy to afford. The average person makes way more than 10.00 an hour. If you stay at work ONE extra hour on ONE day, you can afford Adobe Photoshop and Adobe Lightroom for A WHOLE MONTH!!! When you put it that way, I don't think anyone can turn down that offer. Work 1 extra hour, get the full-most-up-to-date software for a whole month! That 1 hour of work turns into about 30 days of owning the software!! Call me crazy, but you'd be crazier if you said you can't afford Photoshop.
