Type of Button
This is where you choose the type of button that you want to create. You can create Buy Now buttons. These have a set price that you charge for an item. Once the button is clicked, it goes to PayPal and the customer can pay.
The next is a donation button. These are similar to Buy Now buttons. Only there is no set price inside the button. The person can put in their own price once on the PayPal Site.
Then there is a subscription button. The Subscription button allows you to set up recurring payments with PayPal. You can set the number of times for renewal or leave it unlimited.
Then there is a Cart Button. These buttons create a cart on your website that collects what the customer wants to buy and when they are ready, they click a view cart button and head to PayPal and pay.
