They never deliver on time. Also, some of the promotional vouchers/discounts which are shown on the websites, they wont allow you to use that while making payment.
This is my own experience. They showed Rs.3000/- discount on UTV and when I tried ordering, I got the message coupon has been used upto its limits. I could not avail the offer. As soon as I made the payment, the offer was again displayed in there.
Be careful.
