I initially purchased my new iphone 12 in monthly installments, yes I could have paid for it outright, but I didn't see the point in paying ~1k upfront.
I'll amend this by saying that there's also another huge requirement for it to make sense: The new iphone must be necessary for any of this deal to make sense. If it was impulse bought because of this financing offer, then the financing has cost you >$1k
no interest 12/24 month payment tied to apple card.
