Working for free is fine, and a valid marketing strategy, as long as we feel it’s our choice. However, it can breed expectation, so don’t take yourself for granted, or you’ll find others will too.
The marketing environment has changed hugely over the past few decades. Providing information, samples and services for free is now a major marketing strategy in many fields of business. I believe it was Helena Rubenstein in the 60s who first capitalised on the concept of the free sample, giving away a small sample of cosmetics to loyal customers, to introduce them to a new or different product. The practice is still used to great effect within that industry. The purpose of the free sample is to allow the customer a risk-free way of experiencing what is for sale, by allowing them to experience the merits of the product directly. It is seen as a valid expense of the business, a marketing cost. With the advent of the digital age with informational, music and movie products, free sampling has become the norm rather than the exception. The environment has changed. A lot is given for free.
