On the 4th only Hallmark is having a sale 25% off Star Wars items(in-store & online). There are some exclusions, but it looks like it includes the Star Wars itty bittys!
Hallmark with have the annual limited pin set (Lando, Darth Maul, and General Hux) which you get free with an in-store purchase of $15 or more on Star Wars items. Sadly that excludes itty bitty purchases which is silly considering they are itty bitty pins (4/27-5/5).
The online exclusives for May the 4th are Lando and Enfys Nest from the Solo movie.
A BB-9E itty bitty limited edition ornament will also be released.
I will update this post as I find out more.
Other news: The Han and Chewbacca set are available online. And Lobot will be available online on the 4th. Both are already in-stores.
