Emu Therapy specifies that Coupon cannot be stacked together at the same time. Of course not in most cases, unless your Emu Therapy order value is eligible for free shipping, you can enjoy free shipping at the same time as Emu Therapy Promo Code. But you can also enjoy more hidden perks on Emu Therapy, like buy one get one free, or free shipping. Of course, this requires your order amount to meet certain usage requirements.
