Hello,
I am going to share my exprience of my first bus booked by redbus.
This app is very good.It shows many options of buses for your convenience. We can also apply fliter like ac, non ac, sleeper, and many option.
When I booked for first time I got 150rs off from the original fare and 100rs cashback in redbus wallet. Just we have to apply one promo codFIRST to get off and cashback.
