Recently I registered on lenskart.com by viewing its advertisment of getting free frame and I got a msg from lenskart that your account balance is credited with rs 1000.
Purchase it for free.
But at the end by signing up I come to know that this is the only trick to fool customers and a strategy to attract more people. Even though I tried the frame for the first time but felt very dissapointed with the quality.Just a suggestion do not get fooled by fake promotion strategies. Apply your mind.
