Bath & Body Works will occasionally offer the $10 off $30 coupon, but there is no way to know ahead of time when they will be available. One of the best ways to be alerted when the $10 off $30 coupon does become available is through signing up to the Bath & Body Works page on DealsPlus. You will then get an email sent to your inbox when the best offers, including the $10 off $30 coupon, when it become available.
