With fall coming up, Apple unveiled its latest slate of iPhone releases at its launch event Tuesday. The iPhone 8 and iPhone 8 Plus feature a handful of significant upgrades like wireless charging, while the iPhone X includes a fully redesigned exterior and even higher-end hardware.

If you want to get the best deal on an iPhone 8 or iPhone X in advance of its fall release, here’s what you’ll need to know:

When do pre-orders for the iPhone 8 and iPhone X start?

For the iPhone 8, pre-orders will start Sept. 15 in advance of its Sept. 22 launch. On Apple’s end, the company has already started the pre-order process through its iPhone Upgrade Program.

In an email, Apple advised customers who want an iPhone 8 to use the Apple Store app on their existing iPhone so they can get pre-approved for a pre-order via the payment plan program, according to MacRumors. With demand expected to be high for iPhone 8s, this can be a way for interested buyers to lock down an iPhone before stock potentially runs short. For users interested in going directly through Apple, the pre-approval process will end Sept. 14 at 7 p.m. EDT.

Other major carriers and retailers will start offering pre-orders on Sept. 15 at 3:01 a.m. EDT. Already, outlets like AT&T, Verizon and Best Buy have pages with information and signup forms that’ll let you know when pre-orders go live. However, shoppers who want to spring for an iPhone X will have to wait a little bit longer. Pre-orders for the phone won’t open until Oct. 27 ahead of its Nov. 3 launch.

What carriers are offering deals on the iPhone 8?

The iPhone 8 won’t carry the sticker shock of the iPhone X’s price tag, but carriers are still offering a handful of deals to help out with hardware costs.

Verizon will offer trade-in deals for shoppers who get an iPhone 8 and sign up for an unlimited data plan. Trade-in value for phones starts at $300 for current phones like the iPhone 7 and 6S-series and goes down to $100 for phones like the iPhone 5 and Samsung Galaxy S5.

On Twitter, Sprint CEO Marcelo Claure said the company will cover half of the iPhone 8’s cost when you trade in an iPhone 7.

T-Mobile CEO John Legere also announced a similar $300 trade-in deal with old phones for the iPhone 8 on Twitter.

As for AT&T, the company isn’t offering a similar trade-in deal, but will still feature several other offers for the iPhone 8. AT&T subscribers who get an iPhone 8 can also get a 32GB Apple iPad for only $100 and the carrier is expected to bring back its buy-one-get-one-free deal for the iPhone 8 to customers who also sign up for DirecTV, according to Bloomberg.  

How much does the iPhone 8 cost?

The iPhone 8 costs $699 for the 64GB variant and $849 for the 256GB model. On the deluxe-sized iPhone 8 Plus, prices for the same-sized versions will run $799 and $949.
