Once I have planned to visit Agra and searching on google sites to book bus and my bad luck suddenly Travelyaari.com came.
I went to its office in Netaji subhash place and booked 4 tickets for very next day and after 2 hours I called them again asking them to book one more ticket and they said "there is no bus for tomorrow because Taj mahal does not open tomorrow " then I called the man who booked my ticked and he arranged the ticked for the day after tomorrow.
When I reached the station I found that the same tickets was given to 3 different person who were sitting at our seat and when I informed about it to conductor he shouted and told to sit at back and a quarrel took place, and then conductor told us that they book the same ticket for 5 people sometime and he said daily I have to manage like this.
I do not recommend you to use Travelyaari.com
