I recently purchased a sandisk usb 3.0 32 gb otg from snapdeal at just rs 700 while the same thing the retailer was selling for rs 1335 . Its MRP is rs 1500 . So I had saved around 600 rs . The other thing that attracted me was their delivery although that was through gojavas yet I waould say that online purchasing is a very good and efficient way to save money as they provide the same thing in a lesser price
