The popular 20% off, $5 off $15, and other printed coupons are for in-store purchases only, and Bed Bath & Beyond doesn't offer coupon codes for online purchasing.

However, if you've signed up to receive coupons, you might occasionally receive an "online savings certificate," which is good for 20% off a single item. This is similar to the regular 20% off printed coupon, except it must be used online for one item, it's tied to your e-mail address, and it really does become invalid on the expiration date, which may be as soon as a few days from the date you received the certificate.

Note that even with this online savings certificate, you'll still owe shipping.
