Enticing members of a target market to try a product is often easy when the trial comes at little or no cost to the customer. The use of samples and free trials may be the oldest of all sales promotion techniques dating back to when society advanced from a culture of self-subsistence to a culture of trade.
Sampling and free trials give customers the opportunity to experience products, often in small quantities or for a short duration, without purchasing the product. Today, these methods are used in almost all industries and are especially useful for getting customers to try a product for the first time.
Some promotional methods offer free products but with the condition that a purchase be made. The free product may be in the form of additional quantities of the same purchased product (e.g., buy one, get one free) or specialty packages (e.g., value pack) that offer more quantity for the same price as regular packaging.
Another form of sales promotion involving free merchandise is premium or "give-away" items. Premiums differ from samples and free product in that these often do not consist of the actual product, though there is often some connection. For example, a cellphone manufacturer may offer access to free downloadable ringtones for those purchasing a cellphone.
