The current coupon that Allergan gave my office for Botox Cosmetic is a form that we sign and give you with your treatment of Botox. You then take our office receipt and the coupon form and fill out an online form.
The online form will then give you a code that you write on the coupon. You then send the coupon and the receipt to the address on the coupon and they send you a check for $50.
The promotion actually has two coupons per person, so you can actually end up saving $100. The company only gave each office a limited number of coupons, so if you are interested, then you need to get the Botox soon. I hope this is helpful.
