You can send a link to your customer to use a coupon that you
have setup for them together with the product page to use with the
coupon.
Example
:
http://www.yourvpaspsite.com/shopcouponentry.asp?coupon=test&returnurl=shopdisplayproducts.asp?id=3
The link will simply accept the coupon named “test” and validate it and store it in a session so that it automatically populates the coupon text field on shopcustomer.asp when you order.
You will first to create a coupon and then pass it into the
coupon=yourcouponname like the above example.
So if the customer
opens the page, it will redirect to the product
pageshopdisplayproducts.asp?id=3 and then when the customer performs the
checkout on shopcustomer.asp, the coupon field will be automatically populated
and filled with “test” value (just example).
On the next screen, in shopcreateorder.asp, the total
amount will be deducted with the coupon amount depending on your coupon
setup.
