Quick Fact: Pricing The prices marked in stores are without sales tax. Depending on the state laws, all goods might be taxed, or only non-necessities. Sales tax runs from 6-10% of the total cost. Prices are marked by a sticker or price tag on the item. If bar codes for scanning are used, the price should be marked on the shelf with the item. If you think the cashier has made a mistake in ringing up your purchases, say so immediately. The longer you wait, the more difficult it will be to correct the error.
