Just to show you how confusing ON DEMAND (linear cable version) has gotten in the last month or two.
"Superstore" found under "Title" in HD version is now listing both episodes for season 3. First list states incorrectly as 2015. The second list (2017) states $2.99 each.
For now you can watch first list (actually 2017) for free. I guess the old saying: "Garbage in. Garbage out" still holds true for computers.
