Does amazon accept paypal pay in 4?

No. Amazon does not allow any payment to be made via Paypal pay in 4.

Paypal Pay in 4 is a facility provided by Paypal that allows you to make your payments in 4 equal installments within six weeks of your purchase, through your Paypal account. But since Paypal is not accepted as a payment means on Amazon, it is not possible to take advantage of Paypal's pay in 4 service for purchases made on Amazon.
