I don't think that's quite true. The minimum price point on Apple.com right now is $449: https://www.apple.com/shop/buy-iphone/iphone-7

I know a lot of people are saying the SE is dead, and I believed that, too, but it's still there on Apple's web site. Just go to iPhone > Compare, and either click the "See all models" link, or select it (or anything back to the 6) from the drop-down.

The SE is listed as "Available at authorized retailers," but you can still buy the 7, 7 Plus, 8, and 8Plus from Apple.

The 7 is $449.
