CashKaro is best cashback site as per my experience! Because I used other cashback websites as well but I found "CashKaro" a customer service oriented company. Even they are very honest with their users. I will share the proof as well. I went to coolwinks.com through CashKaro in order to get the Cashback of Rs 400. I purchased a sunglass from coolwinks.com but I didn’t get the cash back to my CashKaro account. I know it was disappointing for me.
But I contacted CashKaro team via Twitter and I got the resolution without any hassle. Overall experience was good. I got the cashback credited to my account. And I will recommend using the services from CashKaro.
