I am currently using the app for buying with an account that delivers to my father in laws store since my home address is suspended. I was thinking about opening another buying account only to get items shipped to my address so he doesn't have to cart stuff over everyday. If I were to replace my phone, and get the ebay app on that phone....would it have any link to my account info by the service of the carrier? I did use 1 sellers account on that phone. I would probably have to get a new apple ID.....it would be nice for me to be able to get one paypal buyers account that I can add all these debit cards I'm getting from these different banks to have access to all my funds in one place to spend.
