Usually, in smaller retail outlets, POS displays are supplied by the manufacturer of the products, and also sited, restocked, and maintained by one of their regular salespersons. However, this is less common in large supermarkets as they can control the activities of their suppliers due to their large purchasing power, and prefer to use their own material designed to be consistent with their corporate theming and store layout.
Common items that may appear in POS displays year-round are batteries, soft drinks, candy, chewing gum, magazines, comics, tobacco, wine, food, and writable CDs and DVDs. These displays are also useful in outlets with limited floor space, as there tends to be much wasted space around counters.
The displays are normally covered with branding for the product they are trying to sell, and are made out of cardboard or foam board and/or a covering over a plastic or Perspex/Plexiglass stand, all intended to be easily replaceable and disposable. This allows designers to make full use of color and printing to make the display visually appealing. Some displays are fixed or non-disposable; these may include lighting to make the display more visible and may also contain a cooler, e.g. for drinks or ice cream. Some are no more than a metal basket, with no design on the outside, simply showing a price; these types of display are easier to refill.
