We have added the amount of 1999 which is 19.99 and also enabled billing address and shipping.

When the user fills out the required information he will be able to click the Payment Info button and continue.

Here, the user will have to type his payment credentials. If you have enabled Alipay of Bitcoin in the settings users will be able to use those as well.

The user will see here the value you have setup for Checkout Button Label in front of the custom amount of 19.99, so it is advisable to remove the Label when using custom amounts. The user will see the following default message if the payment was successful and you haven’t disabled the success message from the settings.
