Hi Nancy,
I saw also on their wehsite than it's a subscription plan today to get Photoshop 2017 CC. I am surprise. I remember than I bought Photoshop CC 2014 (v15) in March 2020 from them. It was a one-time paid version. I thought that it was possible to buy Adobe softwares from reseller. Moreover, I bought other softwares from them in the past always with credit card with no problem. They have good prices and an excellent service.
At one point, I got some problems with Ps 2014 CC. Remotely, the technical support service of this website could not fix the problem. So, they updated free to Photoshop CC 2017 (v18). If it was an illegal software, I did not know. I don't want to get in troubles.
Let us be clear :
CS versions were sold with perpetual licenses. The last CS version was CS6
CC versions are all subscription only. Be that CC, CC 2014, 2015 .....etc ALL CC versions are subscription only and the subscription gives you access to the current versions. If you are using a "perpetual version" of CC then it is a hacked, pirated copy and as such illegal.
