Awesome sauce, I finally found these at today 2 different Walmarts. The first one had 3 different sets, all SOTDS, scattered amongst a couple of different shopping carts at the end of the toy aisles. None of them were particularly exciting though, about the most interesting figure was a Kit Fisto. I debated for a few minutes and finally decided to pass.
I did find some much better assortments at the next Walmart though, and they were actually in the original display stand, so there was a good selection. I ended up grabbing three different ones, interesting that the packaging style differs for the SOTDS figures versus the Darth Maul packaged ones.
the first wave Maul figures (Shirtless Savage, Bane, Yoda, etc...mainly as I wanted a Chewbacca to open)
the second and third waves of CW figures (Scuba Ahsoka, Wolffe, etc, best assortment of the bunch IMO)
the SOTDS set with Baby Boba, Quinlan Vos, Cato, etc...
These are great values, esp the Wolffe/Scuba Ahsoka set, but one downside is they seem to have glued the outer packaging to the actual cards in several places, so if you were hoping to keep them minty you can't really extricate them. Also makes it harder if you were planning to trade or resell any of the individual figures down the line.
Still, super happy to have tracked these down and was overall very happy with my purchases today.
