When it comes to acquiring new customers and boosting product awareness on Shopify, $0 products (sample products) are a highly effective tool. By offering a product for $0 as a sample, you let customers actually experience its quality and feel, which can boost purchase intent and help you gain repeat customers. On the other hand, you also need to be aware of the management considerations and risks unique to $0 products. This article explains how to register and use $0 products on Shopify, along with the points to watch out for.
What Is a $0 Product (Sample Product)?
A $0 product (sample product) is, as the name suggests, a product priced at $0. It's mainly used as a trial item or experience sample, with the benefit of letting customers check the quality and feel of a product before purchasing it.
Companies and shops are also paying attention to $0 products as a marketing tactic that can help acquire new customers and improve repeat-purchase rates.
How to Create One

Creating a $0 product on Shopify can be set up using almost the same steps as registering a regular product.
- From the Shopify admin, click "Products" and add a new product
- Enter the required details, such as the product name, description, and images
- Enter "0" for the price
- Configure inventory and shipping settings as usual, then click "Save" to finish
This publishes the item on your store as a "$0 product (sample product)."
Specifications
Due to Shopify's specifications, a $0 product can be ordered either on its own or together with other products.

When a customer purchases only a $0 product, no payment method is shown. (However, if shipping charges apply, a payment method will be shown.)
As a point of caution, since — as noted above — purchasing a $0 product on its own is possible in principle, an issue could arise where "only samples get ordered in bulk." To avoid this kind of risk, you need to control purchases of $0 products. The next section explains the specific methods for controlling purchases in detail.
How to Prevent a $0 Product (Sample Product) From Being Purchased on Its Own
If you don't want customers to be able to order a $0 product by itself (i.e., you want to require it to be purchased together with other products), you can easily block standalone purchases by using the purchase-restriction app "RuffRuff Order Limits."

How to Set a Quantity Limit on a $0 Product (Sample Product)
If you want to restrict "the quantity that can be ordered at one time" to prevent only the $0 product from being ordered in bulk, you can easily do this by using the purchase-restriction app "RuffRuff Order Limits."

How to Automatically Add a $0 Product (Sample Product) to the Cart
If you want to automatically add a $0 product to the cart when a specific condition is met (e.g., bundling a sample with every purchase over a certain amount), you can easily do this on Shopify by using a novelty/gift app.
The blog article below introduces several Shopify novelty apps. Please use it as a reference when choosing a novelty app.

In Conclusion
Offering $0 products on Shopify can be expected to help you reach new customer segments and boost satisfaction among existing customers. However, proper management is also essential — preventing bulk orders of the sample product alone, and only adding it to the cart under specific conditions. By using purchase-restriction apps and novelty apps, you can avoid these risks while running effective marketing tactics. Choose the approach that fits your own objectives and operating style, and be sure to consider making use of $0 products.
