How can I find and purchase a discontinued iPhone model?

The 13 Pro was discontinued in 2022. It would be very very difficult to find one in 2025. There may be refurbs available and the best place to check would be the Apple Refurbished store --> Certified Refurbished Products - Apple

Try Swappa. Unlikely to find a brand new iPhone 13pro, but you may find one in mint or very good condition. Right now there is one listed as new, but the seller has no rating, so I'd steer clear of that one. But there are a couple listed as mint under $400 and the sellers have stellar history. Thing is, they'll all need battery replacement soon; most are listed in the 80's percent wise.

The iPhone 11 is still a supported device. make an appointment at the Genius Bar.

You may be able to get it repaired or get an out of warranty replacement within your budget.

Have you looked at what your carrier may be offering? Many carriers are offering hugely subsidized deals on current model iPhones.

Also PLEASE PLEASE read the link Allan Jones posted above, which I wrote to help people avoid disastrous used device purchases.

That is because the phones could pass for "new", they have brand new batteries, and a full one year warranty.

If you want to upgrade, then you’ll have to spend the money to do so.
