Don’t know if anyone mentioned it, but most cards as I know of, collect points for your purchases,
but Amex is as far as I know, the only card with an actual good use of them.
To pay off/lower the invoices with them!
Save points some years and you get your Apple stuff cheaper.
A Master Card I have, that I mainly use for smaller stores purchases, that not always even take my debit bank card, give payback in some more or less useless stuff. As I seldom use it it’s not a problem to get some towels or something like that every 5-10 years or so.
With Amex I always save my point to get my Apple stuff cheaper. That is useful.
