The Riddler and The Joker from the Batman TV series for less than $5.00

Amazon has got The Riddler for $4.99 and The Joker for $4.33 6" action figures from the 1966 Batman TV series.  Both of these action figures are Add-Ons, meaning that if you're a member of Amazon Prime, they ship for free with a $25.00 order (and their cost counts towards that order).  If you're not a Prime member, they are like any other SuperSaver item and ship free with a $35.00 order.

Each of these comes with a 6" action figure, and display base and a trading card.
