Found SpongeBob 9 packs at a Walmart yesterday in Sacramento, they had 3 pack out got them all. Also had DC pack with scarecrow troublesome truck and 2017/1 trains. Great haul.
Update:
Target now has both 2016/4 and 2017/1 blind bags on East Coast.
Walmart still has only 2016/3 on shelves, but with one exception, Walmart now has the latest 3-Train packs that include the Night Time and Space themes on shelves, as well as Spongebob sets. These are as of 11/7 morning.
I was able to complete my 2016/4 and 2017/1, I was even able to find Platinum Thomas, which I paid $8 to get from Australia a month ago, not to mention the add'l I had to pay to get the 3-packs above. Learned my lesson..
I stopped at one today but looked like someone already went through the box before me as I only found Fruit Chews Thomas, Night Time Emily and Duck.
James Launchers have been found in AUS.
The minis 30 pack is at Walmart on the west coast of Canada
