If your purchase qualifies for a discount, a banner will have been visible at the top of the screen throughout most of your purchase (Red Arrow) leading up to the SECURE CHECKOUT. Keep in mind that it will not be visible on the SECURE CHECKOUT page. By this point the discount will have been applied to your order (Black Arrow). All coupons and promo codes are automatically applied after being embedded in the link you used to navigate to the FTD website.
If you are certain the offer has not been applied after checking your SHOPPING CART SUMMARY thoroughly, return to the homepage and try refreshing your browser.
