It seems like GOG was just in the middle of its Fall Sale, but now their holiday-accelerated Winter Sale is coming to a close. They're going out with a bang, and Wing Commander is once again marked down by 80% for this weekend. This means all DOS and Windows Wing Commander games are available for under $10! This even includes expansion packs and bonus materials such as the official guides in PDF form or DVD quality videos in WC4. The series also makes a great gift! There's enough Wing Commander here to keep anyone busy for a few quite a while.
