I'm also concerned about not receiving my order yet.

I ordered 2 sleeves on 7th August from the dutyfree.io website, got a "shipped" email the next day, and had nothing through yet (UK based).

I've been expecting a customs letter, but not even that yet. I'm starting to get a bad feeling about this ...

I'll be back to update if/when anything ever arrives.

edit1: no customs letter, no package yet. (Sep 12)
