The most common coupons for 20% off and $5 off a $15 purchase are typically for in-store purchases only. Bed Bath and Beyond doesn’t actually offer any coupon codes for their online purchasing. However, when you sign up to receive their coupons, you may receive an online savings certificate which can be used for 20% off a single item. This certificate is almost identical to their regularly printed coupon except that it must be used online and cannot be used after the posted expiration date. Remember that while this coupon is a great option for online ordering, you will still have to pay for shipping. If you’re unsure of how to get the best deal, talk to a store manager or the customer service phone line. They are very helpful and can usually give customers tips on how to save money or avoid costly shipping.
