Look at the top of the receipt to see where it came from, the phone number of the store and the cashier who served you. The receipt might even list the store chain’s number and the store's location.
Go through the list of items you have purchased. In most cases, on a sale item, it rings up as a regular price then subtracts the discount from that price. A new number will appear below the regular price or a subtraction sign and the amount will appear. Each item listed counts for the amount of times you bought it. For example, if you bought four cans of soup, then the can of soup will appear on the receipt four times.
