Navigate to Marketing —> Coupons / Discounts from the home page of your admin area
| Discount Type | Description |
|---|---|
| Percent off a product | Discount is applied as a percentage discount. |
| Percent off entire order | Discount is applied as a percentage discount on the entire order. |

Note: The discount name should be the same for all your price breaks. If you set up a new group of price breaks, then that group will have a different name.
If you have enabled 'option inventory control' for a product, make sure to specify the parent product code (so that the discount appears on the parent's product page) in the field named ApplyToProductCode(s) in Marketing —> Discounts/Coupons, as well as all of the child product codes (so that the discount is applied to the actual product placed in the shopping cart).
For example: Parent product code of PH60045 and children product codes might be PH60045-S, PH60045-M, and PH60045-L. Make sure to specify PH60045 in ApplyToProductCode(s) as well as all of the relevant child product codes.
To apply this set of Quantity Discounts to a product, do the following:
If creating a discount / coupon and the discount type is set to give either a percentage or dollar amount off the entire order, if you do not want the discount / coupon to apply to each product but only once, you need to enable the option Span (ie Buy 10 of any product). Otherwise the discount will apply to each product that is added to the cart.
All the free shipping coupon does it add your store's Free Shipping option to the drop down of shipping choices. It does not affect the price of the products added to the order.
Note: You cannot combine two coupons and/or discounts that discount a percentage off the entire order.
