Amazon.in has launched 'Used & Refurbished Mobiles Store'. From the store, one can buy used or refurbished mobiles for a tiny discount. The discount provided is not worth to go with an already used mobile.
Moreover Amazon says that "A seller warranty for 6 months may be included". This means it is completely on seller whether he provides warranty or not. There is no manufacturer warranty on these products.
Amazon has divided 'Used mobiles' under 3 categories:
1) Like-New: These mobiles work perfectly. They have no scratches, dents or cracked screen.
2) Good: These mobiles work perfectly with no cracked screen but may have scratches or dents.
3) Acceptable: These mobiles work perfectly but may have scratches, dents or a cracked screen.
'Refurbished mobiles' are restored Like-New. These mobiles work perfectly with no scratches, dents or cracked screen.
The delivery times for these mobiles are the same as that for any other new mobile on Amazon.
You can head to Amazon's Used & Refurbished Mobiles Store for more details and buy used or refurbished phones.
