Pros and Cons

Pros	Cons
Keep Amazon Pay integration scope minimum as merchant can use PayAndShip for both new and existing buyers.	In case a buyer wishes to use shipping address saved at merchant site but not on Amazon account, a buyer has to add new shipping address on Amazon Pay Hosted page before proceeding to checkout, which is additional task to the buyer.
