Coupon Codes

Example 1: Setup a coupon to give a customer an X% (percentage amount) or Y (fixed amount) discount (optional: when he buys for more then Z):

1. Add a Price Rule Item Module: CAT_Products (CATALooK.netStore -> Products)

Select: ‘Create New’ -> set ‘Status(kind of use)’ = ‘Bundled/Coupon -> set: Product Name = ‘Coupon’ -> set: Price 1 = 0 -> Add

2. Add Cart Price Rules Module CAT_PriceRules (CATALooK.netStore -> Price Rules)

Select ‘Add Cart Price Rule’ -> set Description = ‘Coupon’ -> select the previously created Price Rule Item from the ‘Price Rule Item’ selector -> set Formula = Z-=-X% or Z-=-Y or X% or Y -> Enter all Coupon Codes into the ‘Coupon Codes (Press ENTER/CR to separate):’ box -> Add e.g.:

abc123

def456

ghi789

3. Setup the CAT_Card module to use Advanced Coupons:

Select ‘View Options’ from the module menu of module CAT_Cart and turn on the option: ‘Use advanced coupon management’

The same coupon code can be used only once by a customer but multiple times by different customers.

Fixed coupon amounts are partial redeemable. The balances will be displayed in the cart module.  

If a customer removes a Coupon Code from the cart it can be reused

Example 3: Setup a product related coupon code

1. Add a coupon code entry box Module: CAT_Products (CATALooK.netStore -> Products)  -> Search for a product -> Full Page Edit -> Attributes -> Text Options / data-entry forms -> Create New -> Name / Title = Coupon; Selections = leave blank; Status = Optional; Control Type = Coupon Code Entry Field -> Add -> Select the Coupon option from the Available Options list box -> Assign. The coupon entry field will be displayed on the product detail site. The same Coupon option can also be assigned to any other product.

2. Setup coupon codes via Product Price Rule (CATALooK.netStore -> Price Rules)

Select 'Add Product Price Rule' -> Optional: [set Description = ‘Coupon’; restrict the rule by Product, Category, User, Role etc.] -> Enter all Coupon Codes into the ‘Coupon Codes’ box e.g.:

ABC1D=5

TF34SFL=6%
