Apple today wrapped up its September event today with a few words about its new retail initiatives, including a trade-in program that should help users transition to the new iPhone 11.

Apple revealed that, alongside the launch of the new iPhone models, it will be offering a new trade-in program allowing those who want to upgrade to pay in monthly installments. Depending one which old device you trade in, you could get the new iPhone 11 — regular price $699 — for $399, or $17 paid in monthly installments. The iPhone 11 Pro would go from $999 to $599 or $25 a month, and the iPhone 11 Pro Max (wow, that’s a mouthful) would go from $1099 to $699 or $29 a month.
