I don't want to let you all down by saying this. But Japanese HIGHLY treats collectibles. Usually when collectibles' goods are gone, they are gone for real. That's why they call that goods collectibles. The purpose of collectibles usually aren't for money, it is a 'treat' for hardcore fans (though some are getting it to resell it) and that's why they make them in limited quantity.
There are some limited qty dolls/figurine made by famous figurine makers in Japan that only cost you below $100 at first, but when that figurine comes out for auction it sold for thousands of dollars worth of money. Sure you can hate those people who bought it only to resell it, but that's the meaning of hardcore fans, how far would you go to get that collectibles? And Japanese are simply like that.
But to make you feel better, this is Ayu, a J-Pop artist, who do this. And J-Pop fans are more civilized^^ and their company love money. SO there's always possibility they'll make more. There aren't much otaku in music world, so you can feel more relieve...
