Myntra promises to deliver in a week, mostly they deliver in three days max. Many times I have placed an order at 5 am., to receive confirmation that it has been shipped within 3 hours and I get the product the next day (and I live several states away). And there is no shipping fee, even for COD on the most insignificant order.
I am a regular online shopper and have experience with Myntra, Jabong, Fashion And You, and lately Pepperfry. The one I would unhesitatingly rank #1 is Myntra. Their returns policy is THE EASIEST. No other site can beat the ease with which you can return a product and get it credited. Often I have got it credited within one working day (cant help contrasting with Fashion and you which takes weeks). They are up to date with end-of-season sales too.
This glowing eulogy is prompted by the fact I just received a few orders from Myntra earlier than expected (as usual) and so am so happy with them. One item (a Scullers bottom) needs to be returned for size issues, but I am content because I know it will go smoothly without a hitch.
Would recommend to anyone without hesitation.
