Just to talk about what I saw out in the wild yesterday when I was out
Silver Mario was very common. I saw it at Gamestop, Target, and Toys R Us.
Pac Man I only saw at gamestop and they had a bunch but did not see him at any other stores. However he seems to be one of the few that lasted til the end of the amazon gauntlet.
Inkling 3 pack I saw at Target and toys r us but in small quantities
The Boy and Girl Splatoon characters I saw most places and are the most common with Silver Mario
Jigglypuff was at both targets without too much issue
I got Charizard, Wario, Lucina, and Robin on amazon and did not see them in any stores
No Greninja's at the toys R Us I visited
Probably going to have to pay for Ness as I don't expect him to ever show up on shelves
Toys R us did get restocked with Dedede and Lucario though which was interesting
