Where do I buy Photoshop outright?

Question

Our business has determined that we will not rent software - where can we buy photoshop outright?

Answer 1

ssprengel asks: "So the reason not to use Adobe software cost-based or legal/accounting-based or merely philosophical-based?"
A legitimate question - As I mentioned previously, as a large corporate business we have made a business choice not to rent software (we are more than three times the size of the Adobe corporation and as such, have many potential users). Our choice is to purchase software because software (to us) is a registrable asset, not a consumable or temporary purchase, and to legally register an asset one must actually buy it outright. Further, we depreciate assets as part of normal tax practices, another essential business task that cannot be done with rented software. That this also equates to a 'reason not to use Adobe software' is simply an outcome of Adobe's choice in the matter. I am not in any way criticising Adobe for this choice - their business is their business - please remember I simply asked if we could purchase the software outright. Other posters have made this some sort of issue beyond this simple question.
The truth is, there are many vendors who provide imaging software that meets our needs (even though I am personally a fan of Photoshop having used it since the early nineties on a Mac, but not so much of a fan that I wouldn't swap it for something more suited to our business, or resort to station_two's levels of sarcasm on a forum such as this :-) .. I do however thank Station_two for advising me that I will not be able to buy updates for Photoshop after purchase, meaning it's probably not worth our while to consider further.
Anyway we all undoubtedly have more pressing issues to deal with so once again I thank you for your assistance, and for your curiosity as to why I asked this question. I hope I have provided you with a reasonable answer.
