Query: Too Flawed to Function

I just ordered four of these, based on reviews. Unfortunately, the covers are so curved that they take up twice as much space as necessary, and don't fit on a shelf together. Something about the combination of materials and glue on the covers has warped them in a counter-clamshell fashion: they look fine empty, but fill them with DVDs and the free edges have spread out an additional 4".These will be returned, and another solution sought.
