I’m building a website for a client that sells antique and vintage jewelry, so there is only 1 available for each item. However, for some of the items, we need to add an option without increasing the inventory. An example is allowing users to select sizing or no sizing for an antique engagement ring (sizing increases the cost). Open to ideas that aren’t too complicated (I’m still learning). Thanks!
Can you explain it a little more with the preview URL of the store?
Hi @mrosemurgy ,
It has been some time since you raised the topic, and I’m unsure if you have already found a solution for your store. However, I would still like to suggest a simple solution that you (and other members) can consider if you encounter a similar issue in the future. The best part is that no coding is required 
.
I recommend using the Easify Product Options app to set up your product options. It’s a user-friendly app that simplifies the process. Here’s a step-by-step guide:
- Start by creating a new option set:
- Add a custom option that allows customers to choose between “Sizing” and “No Sizing.” You can use the Buttons option type or any other suitable option type that fits your needs.
- Provide the necessary details for your custom option, such as additional costs or any other relevant information.
- Assign the custom option to the relevant product(s) on your website.
With these simple steps, you’ll have your product options set up without changing inventory 
. I hope you find this app useful for your store!
