Fermi problem

Obviously, everyone is bored by piano tuners. So, new one!

How many years it would take Russian post to deliver science fiction magazine?

Hints: first you should assume that post would not deliver magazine directly, because every employee, who is interested in that kind of literature should read it  first (employees can be spread all over the county), second location of sender recipient doesn't matter, because shipping time  from sender to first employee and from last employee to recipient can be neglected.
