tag

A price tag is a label declaring the price of an item for sale. It may be a sticker or attached by twist tie or other means.

Some jurisdictions require items (possibly exceptions for bulk good and produce) to be individually marked with the price, or have shelf tags or barcode scanners available so customers can determine prices without consulting store staff. In some cases, unit price is also required. Some jurisdictions also outlaw price discrimination except for different quantities (e.g. quantity discounts are allowed) or different types of customers (e.g. individuals vs. organizations that might be expected to buy in bulk or have better creditworthiness). For example, the 1936 Robinson–Patman Act outlaws this practice in the United States. Many price tags also bear the name of the store.
