Yes, limited editions can be offered on Shopify. This functionality is part of the Shopify platform itself and not directly linked to the WhiteWall app. However, it can still be applied to your WhiteWall products.

Here is how:

1. In your Shopify admin, go to Products.

2. Select the product you want to offer as a limited edition.

3. Since the count must be adjusted for each variant, click on each variant of the product.

4. Activate the inventory by checking the "Inventory not tracked" button.

5. Enter the desired quantity under "Available" before saving your changes.
