Surprise! Hasbro's Kenner's The Retro Collection The Mandalorian (Prototype) figures are showing up in Phoenix, AZ for $14.99 each. (I found them, so it's a legit sighting.) Take care to examine both sides of the rifle for stress marks before making a purchase.   The figure has a gray cape and Kenner blue blasts, so it might be of interest to customizers and open toy collectors just for that.

The DPCI is 087-26-2812, if that's worth anything to you.
