Not Adobe empoyee but do not think there is such a price break. There is one for educators and students.
It you needs are not complex the Photoshop Elementns may suit you just fine. I can be had for under $100. A subscripton to Photoshop is $10/month (offer valid until Dec. 30, 2013). PS has a high learning curve.
You can get a free 30 day trial for each product.
I would contact Adobe Customer Support (not Technical Support), and discuss the licensing issues with them. They can tell you of any requirements, and also the costs. I think that I would call, rather than do a Live Chat, in this matter.
Good luck, and I agree that PsElements might be a viable route, as Curt noted.
Or a perpetual inexpensive Photoline license.
