We were using zooplus for several years, from two countries, and all was well.
Recently, however, we bought two bags. The dogs struggled with the first one, so, thinking they probably got bored, we opened the other after some 1.5 month. It was MOULDY. Covered in fungus, reeked, and was repulsive.
To our complaint - first in years mind you, we don't complain about just anything - we heard it was our fault for not storing it properly (??! sealed, inside the house? Seriously?!), and zooplus thinks there's nothing they can do.
Well then, zooplus, we won't be bothering you ever again.
