Tickets to concert

I am already so exited about the concert tomorrow, rock rock! Legendary KISS will have a concert tomorrow at the Moscow Olympic Stadium. Cool! I bought tickets already in March when I realized that Helsinki concerts were sold out and there will be a concert here in Moscow too. Buying the tickets was another story... One of my colleaques was helping me to find the website where to book them (http://www.ebilet.ru). Then they will call you and confirm your order. Yes and again I needed some help to get it done... Then after few days the tickets were delivered to our office :-) One interesting fact is that even though I paid 3 000 Rubles for each ticket I didn't of course get any receipts... and there is a different price (1 300 Rubles) printed on the tickets. So, I guess someone has a good business here...
