I'm looking into buying PhotoShop, but the only options I am seeing are paying monthly/yearly...is there no way to just purchase the entire program??
One does not buy the program itself but rather a license to use it.
And Adobe has abandoned selling perpetual licenses.
I myself find that unfortunate but that’s the way it is for the time being.
So you can either try to purchase a legitimate license for an obsolete Photoshop version somewhere else (with all the risks that includes) or go with the Cloud license.
