While there is no integration that will allow you to use your Payoneer balance to make your Amazon purchases, you can request a Payoneer Mastercard debit card. This card works like any other debit card out there and will let you make online payments at all online commerces that accept Mastercard, including Amazon. Keep in mind that requesting a Payoneer debit card will result in a charge of $29.95 every 12-month period.
