Can Du still buy the sims 2 at a retail store like walmart, target, best buy etc, and if I can't where can I get a copy of it?

Don't get me wrong, the sims 3 is awesome, the sims 4 is ok but the sims 2 looks and sounds intriguing since there are NPC's, features...etc that the sims 3 and 4 don't have. Plus I have the basic sims 1, sims 3 and sims 4 (along with the sims 3 Late Night expansion pack and the sims 3 high end loft stuff) but I don't have the sims 2 and need to complete the collection!
