Sure, their return policy is good if you bought an item and later decided it doesn't suit your needs - that's an issue that's often entirely your own fault, and they're happy to refund you in the hopes of keeping a customer. That's usually going to be a win-win.
But if you've been sold an item under false pretenses, their return policy isn't a "policy", it's a legal requirement. I'm not charitable enough to use the terms "pretty good" to describe any process where step 1 is defrauding the customer.
Amazon sell counterfeit items but want to avoid the legal responsibility of doing so.
