From a site I found out that there will be a Rick & Morty (Evil Rick) Pops Exclusive that will be a Gamestop/EB Games Exclusive. There is currently no glam shot of it yet but once there we will post it. I believe you can start pre-ordering at your local Gamestop/EB Games.
The SKU for the pop at Gamestop to preorder is (128571). Give that number to the GS associate and they should be able to pull it up on their computer and then you may reserve the pop.
