If you wish to, you can save multiple payment methods on your account and switch between them any time you want.
You can do this easily by implementing the following steps:
1. Go to your customer account
2. In the "My account" section click on "edit" next to "Payment methods"
3. Click on the payment method you want to add and enter the requested details
Before registering your new payment method, review whether you would like to use this payment method for all your payments.
For future orders, you can easily select one of the payment methods already registered if you want to switch.
