I am looking to add a custom color option to some of my production parts through the store. Is there anyway I can put this option in a configurable product with a warning that says something about having to call the company for more information? Any ideas or scripts to do this would help a lot!!
You can try to do this with custom stock statuses. Check this extension : https://amasty.com/custom-stock-status.html
so you can use new status with message "call 1-800??? for more information!"
this extension supports configurable products.
Hope this helps.
