They have a great sale going on this week. Here is a list of the season sets listed in the ad for $19.99.

Knight Rider S1-4
Las Vegas S3-5
Quantum Leap S3-5

I purchased the Las Vegas seasons, they are half the price of what I can find online. And when I was at Hastings they has many other season sets for $19.99, I remember seeing Roseanne but I can't remember what the others were. They also had a few shows like Friday Night Lights S1 and Sliders S3 for $16.99.
