I recently purchased Sony 40" LED TV, though I read multiple mixed feedback about paytm but checked with customer care and bought a Sony LED TV.
It provided multifold benefits:
It provided best price of that time including cashback.
They offered cashback directly in the bank account since there is a limit of 10000 cashback in a month.
The delivery was much faster. Product is in good condition.
Customer service responds well within time most of the times.
