Checkout Config: Discount Coupons« General
Checkout > Configuration > General > Discount Coupons
1. Enable Coupons
This is set to “No” by default. Setting this option to “Yes” will enable the use of coupons codes by your customers when shopping. Coupon codes are then created and managed form “Checkout > Discount Coupons” section in the admin panel.
2. Allow multiple coupons per order
This is set to “No” by default. This option will allow the customer to use more than 1 coupon code per order if set to “Yes”.
3. Affect Tax & Shipping?
Setting this to “Yes” will calculate the discount before tax and shipping is applied. This means that tax and shipping will end up being cheaper than it would without the coupon code being used.
Setting this to “No” will apply to coupon code after tax and shipping has been calculated. This means that you will cover the price of the tax and shipping as you normally would and then the discount is applied to that total (inclusive of the tax and shipping charge).
