When a customer clicks PeachPay's Express Checkout button on a product page, it will
add the current item to the cart
open the checkout window
The checkout window is a compact, sleek checkout form that appears on top of the page, allowing the shopper to enter all information and pay directly from that page.
If clicked on from a page other than the product page, like the cart page, it will simply open the checkout window without adding any item to the cart.
