I've also seen some for the EU version of the S20 line that comes with a clear case... hope that's the case (pun intended) too! Would save me a few bucks hehe.
I got mine from Samsung Canada online store. Mine also has the clear case. Slippery, but does its job at protecting the phone from scratches. Waiting for the Thinfit case from Spigen, which I think will help keep phone from being too slippery.
