A product sample is a sample of a consumer product that is given to the consumer free of cost so that he or she may try a product before committing to a purchase.
A free sample or "freebie" is a portion of food or other product (for example beauty products) given to consumers in shopping malls, supermarkets, retail stores, or through other channels (such as via the Internet). Sometimes samples of non-perishable items are included in direct marketing mailings. The purpose of a free sample is to acquaint the consumer with a new product, and is similar to the concept of a test drive, in that a customer is able to try out a product before purchasing it.
Although an expensive method of targeting customers, conversions to sales can be as high as 90% making it one of the main marketing strategies for certain markets. With effective sampling, marketers can create brand loyalty and assist in the launch of a product through the word of mouth.
Many consumer product companies now offer free samples through their websites, to encourage consumers to use the products regularly, and to gather data for mailing lists of potentially interested customers. Paint chips are samples of paint colors that are sometimes offered as free samples.
