I need to have the coupon set to only be good on 1 product item.

I need to have the coupon set to only be good on 1 product item. I have the coupon for a ticket item but if they want to purchase more then one ticket, the rest needs to be paid for. Example: Each staff gets one free ticket but if they want to buy more, they have to pay.

How do I set that up?

Yes, you can create a coupon where it is applicable only on 1 product.

Example:

If you want to add a Quantity option in the product with different pricing, you can enable Special Pricing and customize each price per quantity.
