When I shop Refurbished Mac without logging in, it shows one price (price A), and for some items, a discounted final price (A').
When I log in with ID.me and shop Refurbished Macs, it shows one price (price B), and for some items, a discounted final price (B').
For all prices listed B < A and B' < A'.
It seems to me that at least my discount applies to Refurbished Macs. I did not go through every product/model or multiple pages, but see attached photo for just one item. All prices while id.me verified are less than the Refurbished prices while not logged in.
