Can I use two debit cards to make a purchase in the Epic Games Store?

You cannot select two credit/debit cards to split the payment at the checkout in the Epic Games Store. However you can use one card to top up your Epic Games Account Balance, then you can make the purchase using this balance and paying the remainder with the other card.

Please note that It is not possible to split subscription payments between different payment methods.

For more information on how to top up your Epic Games Account Balance, refer to How do I add funds to my Epic Games account balance?
