Where can I get Oregon Trail 3rd Edition for Windows, Mac version?

Ebay has the Oregon Trail 3rd Edition for Windows, Mac version for only $2.50. This game hearkens back to the days of the first Oregon Trail, meaning instead of tons of options that made up Oregon Trail 2, you have very few options. Theres only one place you can go to, (besides the fact you can stop anywhere) which is Oregon City. You can also only have five or so people in your group. But besides these points the game is totally Oregons Trail. You can hunt, and you can fish which is a new thing you can do. And you can go down the dalles in a first person veiw (along with floating across rivers.) Amazon has it for $2.95.
