It displays the number of coupons already redeemed and their subtotal just above the input.

It also shows the line items for the two that have been redeemed. The first was an instant coupon redeemed on the product screen for product code SR_00013 and reflects $1 off that product. The second was redeemed on the basket screen and shows a 10% discount off all three products in the basket. You can limit the discount to only certain products if you want.
