I went back to St-Leonard's Walmart today and was surprised. Figurewise they had restocked and had about 20 POC in total: several Storm Shadows, Dukes, Beach heads, Snake Eyes....and only one Alley Viper which I picked up.
They also restocked on the wave 1 vintage style Star Wars and I picked up Dack and Boba Fett, which were also the only ones they had. They had all the wave...until I bought the ones I was missing.
