I am actually from Czech Republic and I am very surprised about your mixed feelings about Filmarena. As far as I am concerned, the main issue you have is packaging towards foreign non-Czech countries, bad cancellation policies and non-real steelbooks covers when preordering few months before the release.
Well, from the perspective of czech customer, I can tell you that filmarena is simply great for us. Not only they provide best prices in our market, they are great at dealing with any problem that may occur while purchasing some of the item they offer. I had multiple issues with changing my mind, misplacing order, cancelling order and so on. And they always helped me and made everything allright.
I hope that I dont sound like one of the reprezentatives of this store, but they are really great. People working in this shop are themselves big Blu-ray and steelbook fans. They make every week youtube video, where they unpack some of the release, talk about the quality of the product they offer, answer customer questions and so on. They actually love blu rays and steelbooks, got there own collections and are simply movie fans.
One has to appreciate that. As I said before, the customer rating and satisfaction in Czech Republic is pretty much the best one. I am deeply sadenned, that these positive experiences does not appear to be worldwide universal. Hopefully, thing will get better.
