How do I offer coupons for my customers to redeem?
If you want to offer a coupon, you need to first enable the coupon system:
Go to: Admin->Modules->Order Total->Discount Coupons (ot_coupon).
If it's not already installed, click Install to enable it.
Now, in your Admin area, you have a menu item entitled "Gift Certificates/Coupons". Click on the Coupon Admin option.
Next, you create a coupon by clicking Insert. (Or Edit to edit an existing coupon.)
Fill in the details.
If the coupon is for a percentage discount, enter the percent sign after the number.
If the coupon is ONLY for free shipping, check the free shipping box. (This ignores all the % or amount discounts, and makes the coupon ONLY apply to shipping.)
You can enter a coupon code, or if you leave it blank, the system will generate a random code for you.
Save the coupon.
Now you can either take the coupon code and manually give it to your customers in advertisements (in print or on your website) or you can click the Email button and send it to a list of customers.
If you want to set up restrictions so the coupon applies to only to certain products or categories, click the Restrictions button to set them up. You can do this at a later date if you desire.
When a customer adds something to their cart and proceeds to checkout, they will see a spot to enter a coupon code ... on the Payments page.
Once they fill in the code and press Enter, it will be checked for validity, and if it is valid and not restricted against what's in their cart, a Success message will show on the screen, and their order Total will be adjusted appropriately.
If they wish to remove a coupon, they can enter a different coupon code, or they can type "REMOVE", and press Enter.
