Abstract: A device includes first, second, and third components. The first component scans a coupon. The coupon is moved from the first component to the second component after the first component scans the coupon and the coupon has been validated. The second component holds the coupon and other coupons associated with just the current checkout session until the current session has been successfully completed, at which time the coupons are moved in unison from the second component to the third component. The third component stores these coupons, together with additional coupons associated with other checkout sessions. The first component returns the coupon where validation of the coupon has failed. The second coupon permits a user to retrieve the coupons associated with just the current checkout session where the current checkout session has been unsuccessfully completed, without the user having to look through the coupons associated with the other checkout sessions.
