Hello, thanks for reading this.

I would like to have a timed promotion on a website for members.

I want to send a promotion to them via email that will have a random confirmation number on it. I would like to keep it unique to each person, so each member will have a separate confirmation number.

When they enter the site and type the confirmation number, they get a discount (for example).

I currently host online with hostmonster.com. I use PHP/MySql.

How can I get started figuring out how to do something like this? I was even hoping to have an expiration date assigned to each promotion code.

Thanks!!!
