Surplus Stores in Russia

I couldnt find any treads about it so I decided to make one. Does anyone know any surplus vendors, markets or stores in the following cities; Moscow, St. Petersburg, Vladavostock and basically any town or city along the Transiberian railroad? Next summer im going on basically a European trip from England to China and want to try and get some cheap camouflage rather than buying them overprice over the internet. Thanks for any help in advance.
