Unfortunately you'll have to wait until you receive your package, then post plenty of photos of what you receive, including all documents, packaging and paperwork. I won't authenticate from the photos on their site because, of course, they are photos of an authentic item. Reebonz, so far, has not onsold any fake
Prada that I am aware of, and I have bought previously from there and received authentic product. And yes...different color hardware is sometimes exclusively regional. Don't know why but that's sometimes how they do it.
