I bought a samsung galaxy s2 from deals.sulekha.com around a month back. The price on this website was full 4000 less than the next best price in the market (letsbuy / flipkart). The delivery time was a bit longer than expected.
Probably because the courier company did not deliver to one of the most important business area of Bangalore, and the phone was shipped by indiaplaza but guess that is ok.
Note: The prices have gone up now
