Some time ago Tesco were selling the interactive Chewbacca, Kylo Ren, Stormtrooper, and Darth Vader figures for a mere £30 each. I snapped those up.
Sadly, this C3PO isn't in the same price bracket, but it is less than half RRP, at £56.99. Now, I wouldn't have paid £120 for any of these figures, and arguably it is still waaaay pricey at £56.99, but hopefully this will be of worth to someone.
Oh, just realised that the Vader, Ren, and Stormtrooper are going for £69.99 if anyone is interested - again, nowhere near the Tesco deal from way back when...
