Their books were wrapped in cardboard before...?
However, they are still sending me other small items in huge cardboard boxes out of all proportion to their contents. Sometimes you have to have a really good nosey inside acres of empty cardboard box to find it!
And the worst thing is the new plastic has no recycling information on it?
Just fedup that Amazon have gained such a huge position in the world marketplace without taking any responsibility. (And I know that's how the world works and it is my choice to use them!)
