Update: Forum member starfire2 called LEGO and confirms with us that this early promotion is only if you order 10225 R2-D2. All other regular Star Wars orders will have to wait until May 4-5 before the promotion is active.
Seems like LEGO Shop at Home really started their May 4-5 promotion early. In addition to free shipping on orders above $75, forum member Muntz reports that he also got a R2-D2 Poster as well as the TC-14 Minifigure by purchasing 10225 R2-D2. Note that you will have to make Star Wars purchases to get the poster and the minifigure. Order here: USA | Canada
