Target is now listing their shared Exclusive Retro Collection 3.75-Inch Wave 1 figures as discontinued. Above is a image confirming this. Per my source the warehouses for my area has 0 on hand and no future shipments are expected. My local stores has not had any of these for over a week or so now.
If you missed out on these at Target don't worry as these are a shared Exclusive and you will have a chance to buy them from online retailers later on in the Fall.
