I have a remainder balance of Rs. 50/- in Gift Voucher can I redeem it on my next transaction?

A gift voucher starts with 8

Gift vouchers can be used multiple time for transacting till the total value is used/exhausted and is under the validity period. 

A winpin can be used only once and the partial payment can me be made through a different payment mode including gift vouchers. 

Certainly, you can use the balance amount of the Gift Voucher (i.e. Rs. 50/- in this case) in your next transaction with BookMyShow.
