Ok so now I've changed the code so that it increments the price by 50p per day, up until the end date that you specify in the script.
I've also added a promotion code variable, and a promotion discount variable to the code. So now if you type 'test' in the promotion code box you will recieve a 15% discount on the order.
Obviously the ideal way to assign promotion codes to returning customers is to generate one when they buy something the first time, store it in a database along with their details so when they come back the code they entered can be checked against the one stored and discount given if necessary. It can also be flagged that they have used their discount and are no longer eligible. This can be done quite easily.
I've added a little bit of javascript just so people dont go submitting blank forms :hyper:
Here's the code
<html>
<head>
<title>Sample NOCHEX checkout</title>

p, input, textarea {

padding :3px

h1 {

}
.bg {

.white{

</style>
<script language="JavaScript" type="text/JavaScript">
