Is there no way to purchase Sims 2 Ultimate Collection?

[marieruth]

I missed the temporary free release for the sims 2 ultimate collection, and I was hoping that maybe I could buy it. I own a few physical copies of the main game and some expansions, but not all of them. Nothing shows up when I try to search Origin, and it would be great if I didn't have to use discs to play the Sims 2. Is there no way for me to buy it or anything? Any help would be appreciated.
