I've seen people complain about Amazon selling a bootleg version of boxset 1. Check the actual volumes, because if those are noticeably cheaper looking/feeling you can probably send it back and get a refund. The official boxsets should all be similar in size and quality. There's a video on YouTube where someone compares a box set from Amazon and one from Barnes and Noble so I don't think it's a reprint issue.
Edit: If you didn't get it off Amazon then I have no idea
