So they can buy the copyright of pictures from other magazines, even the competitors and use as cover? I don't think it's quite common but I remember seeing this happen before.
It's actually not all that bad. The editorial content is somewhat interesting, the focus on beauty stories is good, and there's at least one non-reprinted huge editorial featuring Eugenia Volodina in every issue
So basically it's predictable and repetitive but not a complete waste of time.
