How can I automatically tag $0 orders in my online store?

[AdCreates]

I am trying to figure out how to automatically tag $0 orders (this are replacement orders that are manually created by our CS team). 

1. is it even possible?
2. How should I build it?

TIA

Yes, it's possible. You can build a condition that checks order / currentTotalPriceSet / shopMoney / amount.

The workflow would look like:

• Order created
• Check that variable
• If true, Then: Add order tag

You may also want to add a check for the "manual" part. If that's done in the Admin, the variable order / app / name will show up as "Draft Orders".  You could add this check to the same condition as above.
