On the flip side for Amazon,it feels unfair that the seller has my contact details and can use it to send me emails asking for reviews and to market their other products even when I've opted out of marketing emails. I've had a few counterfeit products where the seller just hasn't responded and I've been refunded but left with the counterfeit item, which doesn't sit well with me. The comingling is an awful problem, and if there were another site that offered next day delivery on a variety of goods with guaranteed wualotythat was more expensive, id swap in a heartbeat.
