I have signed in both the affiliate programs like Flipkart and Amazon. While I have already received payments from Amazon, the Flipkart payment procedure is still pending. I found Flipkart to be a less user friendly than the Amazon.
Whether you talk about their interface, their terms and conditions and even the payment procedure, I didn't find Flipkart that accommodating like Amazon, even though their customer care responded quite promptly.
Friends please share your experience and also suggest other affiliate programs which you found more convenient and better in all aspects.
