Went to my local Target this afternoon and saw that they had a bunch of older iPhones on clearance (still new, in the box), including the iPhone XS, iPhone XS Max, iPhone 12, iPhone 12 Mini, iPhone 12 Pro, iPhone 12 Pro Max, and iPhone 13.

From my understanding, Target recently stopped selling phones through Target Mobile, so these may have been old devices that were sitting around in back-stock for a while.
