Amazon has a history of being surprisingly inflexible with its payment methods. You can pay with a debit or credit card, you can have your bank account charged directly, and you can finance a purchase using Affirm, but it famously doesn’t accept PayPal or other competing platforms for payments. It did, however, add Venmo as a payment method last year. That’s going away now, though, as Amazon has decided to part ways with PayPal-owned Venmo.
