Rapid Preorder | Presale

We kept losing sales every time a product went out of stock the customer
hit "sold out" and left for good. Now the product page switches to a
preorder button automatically, and we capture the order instead of the
bounce. Setup took about ten minutes and the button matched our theme
without touching any code.

What surprised me is how much of it is presale revenue we simply weren't
collecting before. Restock day is no longer a scramble either the orders
are already in.
Amazing application
