We have a promotion coming up where if a guest spends $50 or more in product, they get a free travel-sized hair mask. If at all possible, we would like to be able to create an offer for this, so that it automatically adds it to a ticket that reaches $50 before tax, so that the stylists won't have to remember it. Then they could just see it auto-populate on the checkout, and grab the product for them. That way our inventory stays accurate for the promotional products we have in stock!
