One of the major differences between the Amazon and PayPal payment methods is that, in the case of Amazon, you can get a cash back rebate on any purchases you make, regardless of the method of payment used. This is one of the biggest perks for using Amazon's credit card payment service, and if you're using this method to pay for products with Amazon's other services, you'll be able to avail of a discount of over 70% as well.
In other words, using this type of payment method will ensure that you can buy everything you want without having to worry about spending too much money. The only downside is that you won't be able to avail of the Amazon Prime members-only discounts.
On the other hand, you will have to pay some fees and charges when using this payment method. These include payment processor charges, bank charges, and other costs for processing transactions. Although these fees are often lower than those charged by other companies, they will still add up to a lot. If you don't plan to use the Amazon payment method very often, then this might not be such a big problem for you, but if you're going to be using the Amazon service more frequently, it would definitely be a good idea to avoid using this payment method.
When you're using a debit card to pay with, there's also the risk that the card will be declined due to insufficient funds, even though the transaction is made through the same payment method. As a result, it would be a good idea to go with a PayPal account, as there is always the possibility that the transaction will be approved and the card will be debited from your account with your own funds intact.
As for the other services provided by Amazon, the company also provides a merchant account, which means that the retailer pays only a small fee for this service. The reason this is offered is so that the seller can have the ability to . . . . . . accept payments through a payment processor in other countries.
The main thing to remember when choosing between this and the traditional methods of payment is that, when you choose an Amazon credit card payment method, you won't be able to use the “credit” part of your card. You will need to show proof of identity before allowing the card to be used. In order to get the most out of this payment method, it would be best if you'd get a second card or two, so that you'll have the ability to use it in case your first card gets declined.
