Hi, I am currently trying to develop a script that can do these functions.
For customers tagged with "VIP"
For customers tagged with "Elite"
I realize that only one script can be active at all times, so is it possible to make a script that contains all of these into one?
I have a script that can give a customer a certain discount on one specific shipping, but not all of the above.
You can indeed! A customer object is available via scripts if there is a customer available to retrieve and this object has a list of tags associated with that customer. You could use that, combined with the list of shipping rates available, to apply a discount to any existing rate based on a customer tag.
There is more info on what you can get from within scripts at https://help.shopify.com/en/manual/apps/apps-by-shopify/script-editor/shopify-scripts
If you need a hand feel free to shoot me an email.
