Sale labels are an important part of the retail industry. They are used to identify items that are on sale, and can be found in a variety of shapes and sizes. The term 'sale labels' can refer to two different types of labels: tags (4 letters) and redtags (7 letters). Tags are typically small pieces of paper or plastic that are attached to items with a string or adhesive. Redtags are larger labels that are usually printed on cardstock and feature a bright red background. Both tags and redtags are used to indicate that an item is on sale and can help customers find discounted items quickly and easily.
