How can I exclude certain items from minimum order amount calculations?

[LoRePasta]

I need an app that allows me to have only certain items apply towards the minimum order amount as they fill their cart.  We offer additional products that we don't make money on so i would like to exclude those from applying to the minimum.

Yes it is possible to exclude certain items from the minimum order amount by using the Cart Lock https://apps.shopify.com/cart-lock app easily. Here is how you can do it:

1. Open the app and click on the "Add a new rule" button.
2. Click "Add a new condition" and select the "Cart subtotal" then put your minimum amount like 25 in the "Block if less than" field.
3. Click "Add a new condition" again and select the "Products" then add the related products.
4. In the "Error message" field, add an appropriate message which will be displayed in the checkout page.
5. From the "Match conditions" field, select "ALL".
6. Save the rule.

Now your customers cannot checkout specific products if they don't meet the minimum order amount.
