Amazon has also started to take preorders for Solo: A Star Wars Story 3.75-Inch products as well. Just follow the link. Some of the new Force Link 2.0 products are listed as in stock and ready to ship. Be sure to buy products sold and shipped by Amazon and not a 3rd party seller.

Update: Almost everything is in stock and ready to ship now. Minus Landspeeder and Falcon. Those 2 are currently still listed as Preorder.
