I recently visited mi service centre in koramangala Bangalore there I saw a notice that they are selling redmi 1s @4999 for a limited time at their service centres.
bhaiyu available at ebay too for rs4999 (yup the same refurbished one with six month mi official warranty [which is as good as nothing ]
use 15 ebay deal to get rs 500 off
pay via mobi to get rs300 cashback
add money via that 10% mobi offer that is running to get additional rs100 off
