All the windows PC versions on US Amazon are 79.00 and up. The benefit of Amazon is that they are very ethical and have been wonderful about helping me re any needed replacments for damaged disks, have repaid me shipping in advance and the sellers are very respectful of Amazon too and have great followup with me on many purchases over the years. High marks.
If you do get it, try to make sure you get good condition CDs case WITH artwork (no generic cases) AND the manual. they are worth looking for
just a note, that one you linked to is Mac .
