It is so hard to find and sell used products online. I know there are tons of websites which allow listing of such things. But, they ask you too many questions, you have to go through complex registration process & most importantly your phone number is exposed to public and spam bots. Roopit is different from those. I loved the way they put it on their FAQ:
How do I Login/Register?
You don’t. There is no Username or password. Nope. And, We don’t need your e-mail, your mother’s maiden name or your childhood favorite hero. But, we do need your mobile number. Roopit identifies you with your mobile. If you are selling, You post with your mobile number. If you are buying, You receive the contact details of the seller as an SMS on your mobile.
You can track a product via SMS which you are looking to buy. Simple! Just send what you are looking for to 9916766748. For ex: “Maruti 800”.
