Batman Animated at Sam's
 

All 4 sets of Batman: The Animated Series for $21.50 each at the Sam's Club in Hilton Head, SC. YMMV locally.

I think there was supposed to be a whole group of animated series on sale at Sams that someone posted earlier. Unfortunately I haven't seen any of them.

For some reason, Sam's only stocked like 2 copies of these sets. I wanted some myself, but they told me that the stores will not be ordering any more sets.
