The way to read a retail price code depends on the retailer, but some retailers use price tags with prices that end with .99 to indicate that the item is full price and prices that end with another digit to indicate a discount price. As of 2015, this is the practice at Target, Land's End and JCPenney.
Kohl's uses letter codes on the price tag. When a consumer sees the letters "NM" on the shelf tag, this indicates that the item has a new markdown. If there is an "S" on the item, it indicates a sale, and if "GV" is on the tag, it indicates the item is a great value, and the price is only valid for two days or less.
When looking at a retail tag at Costco, a price ending in a 7 indicates that the item is a markdown. If there is an asterisk on the price tag, it shows that Costco is removing the item from the store's inventory.
Clothing retailer American Eagle uses prices that end in .95 to indicate the item is full price, but if the item ends in .99, the item is on sale. Prices are always subject to change, and a price tag indicative of a markdown does not guarantee a good deal.
