Bookmy show is a good online website to book movie tickets, drama, and for various online events concerts.
I had a very good experience with book my show, I usually book my tickets through this online portal.
If you have a credit card that offers you book one ticket you get another absolutely free, or you can get 50% discount on your movie tickets depending upon credit card features.
If there is problem with the server and money is debited through your account, amount will get credited into your account.
Bookmy show had tied up with IPL last year where you can buy tickets and watch the match at stadium so it provides the convenience to avoid longer queues.
