I've been making rounds at local Walmart looking for the new wave of Amiibo (Walmart usually has them for 12.96 instead of the new 15.99 price), but Snake was the only one I couldn't find.
Happened upon Target having them in stock for 12.99. You should see "See low price in cart."
Also see Pichu and Pokemon Trainer, although Pokemon Trainer is only available for pickup if it's in stock near you.
I was able to get BestBuy to price match for me since I'm closer to it than Target.

Happy Amiibo hunting!
