This is Sophie from Handmade seller support.
In order make a buyer return with a coupon, you can create a promotion with a Single-use claim code.
To do so, go to Inventory - Manage Promotion
Whether you create a Money Off or a Buy One Get One promotion, the procedure is the same.
Here, I am going to take the example of Money Off
Step 1 Conditions
This step is pretty straight forward, you just have to choose the condition of the promotion.
Because you are using a coupon system, you can choose the same options as above.
You can of course choose a product selection if you don’t want to apply the promotion to the entire catalogue and select an amount off instead of a percent off.
Step 2 Scheduling
This one is even more straight forward, just select when the promotion starts and ends.
Step 2 Additional Options
This is where you are going to choose 1 code for 1 customer, select the option as the image below :
Then Review and Submit the promotion.
Then, when you have an order, you have to go back to Inventory - Manage Promotion - Manage your Promotion
Go to the promotion you wish to issue the code and go to Manage claim codes.
Then, as a group name you can put the name of the buyer or the order number and click on Create.
Once the code is created, click on Download and click on the document to have the promotion code to give to your buyer as a coupon.
Important: Please note that the code is automatically generated so you will have to create a new claim code for every order.
By entering this code, the buyer will have 15% Off in his next purchase. This code can be used 1 time only.
