I purchased a bootleg pressing of Stories a while ago and yes, the audio sucks and the packaging is flimsy. It is definitely not worth having.
You can tell the difference between the bootleg and official pressings by the included inners, a spine mis-print, and the colour of the labels/cover (compare here):

There is also a new bootleg pressing of Dry on red vinyl that has been showing up on eBay.
