Core Competency

What is Palmer's core competency? Their PRODUCT! This is a very small company that was founded well over 100 years ago and has remained small by todays standards. Rarely, do you see advertising for this product on television or even magazines. They rely solely on their devoted followers and word of mouth. They know their product is awesome and know that anyone who uses it will be instantly impressed with how soft and supple their skin is after using it. With all of that said, why would they have to advertise?
