I have a oscommerce shopping cart site that is most recent and in need of 2 functionalities:
1. Have a coupon code option where admin will generate a coupon and set the date for expiration.
2. Option for customer to schedule a delivery or pick up both date and time option when they choose for either delivery or pickup as shipment. The admin must be able to restrict the hours say Customer can pick up or sechedule a delivery only the days the admin want and hours like 5pm to 6 pm etc by admin control. The delivery should be included on email. Discount should work on shopping cart.
The site now has a delivery option as store pickup and free delivery module. So If you are installing the above code you will need modify the existing code and I can send you all code for you to modify it.
