You must write a script that enters an "AWD code" and a combination of "Rate Code" and when applicable, "Coupon number" against the [login to view URL] web site and returns the best rate.
Example, you log onto the site and rent a car from one location to another - using three letter airport codes, like IAD to LAX or for same station rentals, like IAD.
One the next screen you may enter an "AWD" or Avis Worldwide Discount code, such as Z190301 or E190300 and the result screen will give you a rate for each category of car.
This script or "spider" must accept the input of new AWD's and rate code combinations and store them so that when a new price request is made, all existing known AWD and rate code combinations are checked.
Try the [login to view URL] site to see for yourself how the pages are returned, and then make your bid.
Access to this script should be on a website, with password access and a sign-up screen that requires an approval from the site administrators.
No backdoors and all rights go to the buyer.
