RedBus.in is one of India’s most popular bus ticket booking and reservation service, which incidentally released apps for the Windows 8 and Windows Phone 8 platforms earlier, with a great Metro UI based experience. But now, they have not only released updates to these apps, but also added a bit of an exclusive offer to them. With the RedBus.in app on Windows 8, you get Rs. 75/- off on a ticket, if it costs more than Rs. 500/-, till December 31st, 2013. Considering this is the holiday season when a lot of bookings are done, this seems like a perfect match for Windows 8 users wanting to book tickets for most destinations in India.
