Samsung has kicked off a double-value trade-in program for buyers of the Galaxy S9, S9 Plus, and the Note 9.
The company is willing to pay more than Apple will for a used iPhone X in good condition, so long as the person is buying one of Samsung's newest flagship Galaxy devices.
Apple offers up to $525, while Samsung's temporary program will offer up to $600.
But that offer also underlines that Samsung normally pays significantly less than Apple. After the program ends on November 3, it will only offer $399 for an iPhone X.
The latest offer isn't quite double for the iPhone X due to the $600 cap, but the trade-in value of all other devices that Samsung normally offers up to $300 for is doubled.
It's currently offering $550 for the iPhone 8, or $200 more than what Apple is offering under Apple GiveBack, and $300 for an old iPhone 7, $100 more than Apple's offer.

Phones need to be in a good and working condition for owners to receive the listed offer when purchasing eligible Galaxy phones.
Besides the iPhone X, the only phones Samsung will pay $600 for include the iPhone 8 Plus, and the Galaxy S9 Plus. Samsung has published a full list of its current offers.
To get the double trade-in value, buyers will need to purchase a Galaxy Note9, S9+ or S9 from a participating carrier or retailer by the November 3 deadline.
After buying a new Galaxy, owners will need to use the Shop Samsung app to send in information about the purchase and the trade-in device by November 17.
Samsung will then check the trade-in device for damage. If it is eligible, it will pay via the buyer's Visa Virtual Account around two to three months later.
