I prefer online shopping, there are various such portal, which offer online shopping but one of leading is flipkart, I am user of flipkart and totally satisfied with their service, support, delivery.
I have bought various product like Philips trimmer, puma shoes, a fast track watch, and mi4i mobile, in all shopping I found better experience, all products are genuine, I can say that for electronic products flipkart is best, So I recommend for electronic products even u can buy other product also, prices were also less compared to other online shopping websites, best customer support,
