I just checked on amazon, and I couldn't find it, and last season it was put up for pre-order toward the beginning of April, and released in August. It also seems that on amazon, they have every other popular shows currently ending season: scandal, revenge, greys anatomy, and resurrection, but not Once upon a time. I have the first two seasons, and I would like to have the whole series. Should I be concerned? Also, same goes for Once Upon a Time in Wonderland.
