He's mad that RetailMeNot made discount codes with his store name that got him sales. Last click nonsense. He's an idiot. We're poking fun at him on FB.
Kogan is a dumbass. Everyone knows that a 'discount code' field in a checkout process is a huge bounce factor. Particularly when you don't even have frequent codes. Eliminating the discount code box is conversion optimization 101.
Good thing is that if someone like this Kogan dude really makes that much money, then someone who can sell him conversion optimization can probably make a fortune in consuling fees.
