Limiting Coupon Usage
Coupons are a great way to attract visitors to your business and encourage them to make a purchase.
You can control when your coupon can be used, what it can be applied to, and how many times it can be applied.
To limit coupon usage:
Go to Coupons in your site's dashboard.
Click +New Coupon.
Select a coupon type and enter the coupon code, name, and discount or offer, if relevant.
Choose what you want to do next:
Limit which items the discount applies to
The Apply to drop-down is where you select the items a coupon applies. The options vary by coupon type and whether you're using Wix Stores, Wix Bookings, or another business solution.
Here is an example of "Apply to" options for Wix Stores:
All products: This coupon can apply to multiple products in a customer's cart.
Specific product: You select a specific product.
Specific category: You select the category the coupon applies to. This coupon can apply to multiple products in a customer's cart.
Minimum order subtotal Enter the minimum about above which the coupon applies (e.g. Coupon good on purchases above $50).
All orders: Available with the Free Shipping coupon.
Tip: To apply a coupon to a group of store products, you can create a hidden category containing all those products. Then, you can apply the coupon to that category.
Limit the dates your coupon is valid
You can create a coupon with a time limit (e.g. Offer good in July only) or create one that can be used at any time.

To limit when the coupon can be used, deselect the Don't set an end date checkbox and enter the end date.
Notes:
The time of day a coupon expires depends on the time of day it was created. For example, if you created the coupon at 7:40 PM, and it is set to expire July 31, it will expire on July 31 at 7:40 PM (your time zone).
You can manually deactivate or activate a coupon anytime by clicking the More Actions icon

next to the coupon and selecting the relevant option.

Limit how many times the coupon can be used
You can limit the number of times a coupon can be used (e.g. offer available for the first 50 customers) and prevent the same customer from using a coupon more than once.

To limit the number of times a coupon can be used, select the Limit the total number of uses for this coupon checkbox and enter the number of times.
Note: Multiple purchases by the same customer or by different customers are both counted.
To let customers use a coupon only once, select the Limit to one use per customer checkbox.
Limit a $ or % discount to 1 item per order
When creating a price or percentage discount, after you select what it applies to (e.g. all Wix Bookings services), you can select how the coupon is applied when there are multiple items in the order.
For example, select Apply once per order to limit the use of $ Discount or % Discount coupons to one item in a particular order.
This means if you have a 20% off all yoga classes coupon and a customer purchases two classes, the discount only applies to the less expensive class.

Tips:
Coupon codes are not case sensitive.
You can use the free Bulk Coupon Creator app to generate bulk codes.
