I'm sorry you're having these troubles. I wouldn't have a problem with him keeping the membership, as long as he's really canceling like he's supposed to, but if he never buys the DVDs anyway, I don't see why he'd bother with it. I know how you said he justifies it, but I still don't see the point. If he's not buying DVDs that often, anyway, it would just be easier to get them when he feels like it in the stores, especially those that offer discounts (or online).
