Where can I buy Sims2 Seasons?

I checked Amazon, and they were only showing pre-owned copies, which makes me a bit nervous. Wal-mart, Gamestop, Best Buy, Fry's and Microcenter all did not seem to have it. I looked on origin.com, and for a minute I saw where I could download it from EA (which would be fine) but then it asked for my country, and none of the choices were United States of America. I could choose Hong Kong, Thailand, South Korea, and a few other countries where I do not live.

I'm not looking for a torrent, pirated copy, or anything like that. I'd be fine with a purchased digital download from a reputable site, or a physical disk, either from a brick & mortar store, or one that would be shipped to me.

Yes, I know that Sims3 and Sims4 are out. I am not looking to buy either of those right now. I'm only looking for Sims2 Seasons, and Sims2 Pets. I found a new copy of the Pets and Mansion & Garden bundle on Amazon, so that's all set :)
