Star Wars: The Last Jedi Movie Merchandise

We're hoping Star Wars Episode VIII: The Last Jedi answers the following questions presented by Star Wars Episode VII: The Force Awakens: Is Luke the 'Last Jedi'? Is Rey the 'Last Jedi'? Is Rey Luke's daughter? Is Rey anyone's daughter, considering she could be a humanoid manifestation of aggressive midi-chlorians?? Even if it doesn't answer all our questions, we're going to love this film and grab all the Last Jedi t-shirts, accessories, and apparel we can before watching, re-watching, and re-re-watching Episode VIII!
