The Eucerin lotion coupons on CouponSherpa.com are under the section entitled Grocery Coupons.

Next, scroll down until you reach the "E" section of the alphabetized list of manufacturers, and click on the Eucerin link. This pulls up a complete list of all available Eucerin coupons, if any.
RxPharmacyCoupons.com also occasionally lists Eucerin lotion coupons. Click on the Rx Drug Coupons tab at the top of the home page, located between the Questions and Participating Pharmacies tabs. To view the resulting list entitled Pharmacy Discount Coupons: Prescription Medication, choose to sort the coupons either by category or alphabetical listing. Eucerin coupons, when they are available, are classified in the Skin Care category on this website.
As of September 2015, the Eucerin coupon available on RxPharmacyCoupons.com is not a printable coupon, unlike those on CouponSherpa.com. Rather, it is an invitation to register for an account on Eucerin's website and receive a coupon for a discount on any Eucerin product.
