On Amazon, you can add/remove and change the payment method. To make the payment fast, setting up the default payment method could be the first step. This could improve your online purchasing experience at Amazon.
With the help of the default payment method, you can add credit and debit cards. Amazon accepts popular credit and debit cards for ease of use.
Amazon.com Store card can also be used to set as the preferred payment method. If you're a Prime member, you can make use of the Amazon.com store card to earn 5% cash back for every eligible purchase you make at Amazon.
Some payment methods are excluded from adding as a default setup. If any of the regular payment methods are available on the default payment setup page, Amazon may add the exempted options in the future.
Updating the default payment method will not alter the payment process for an existing order. It will work only for your future purchase at Amazon.
Once the validity of the card is ended, you have to configure the default payment option with new card information for seamless purchase.
