From here, you can select the items the patient wants to purchase and how many they want of each. The price is listed since the patient is not charged a pre-set fee, they are charged the price of each item they purchase in the package.
In this example, the patient has to buy 200 units of any toxin to receive a free filler. If they choose 100 units of Xeomin, 50 of Jeuveau, and 50 of Daxxify, the total is 100 multiplied by $12, 50 multiplied by $10, and 50 multiplied by $17.
