I’m in the U.S. and had pre-ordered the volume 2 DVD from Target. I got an email notification today from Target that there’s a delay in the delivery date, and requesting that I approve the delay to keep my pre-order. I went to Target’s site (not using the link in the email, of course) and gave my approval, so I still have the pre-order with them. The email confirming my approval gave a delivery date of mid-September. I just checked and Target’s still accepting pre-orders for season 1 volume 2 for DVDs and for Blu-rays again. Blu-ray pre-orders were sold out before. I’m not finding pre-order options for volume 2 offered elsewhere. Why it’s just available on Target, I don’t know.
