Today only, Pottery Barn and Pottery Barn Kids offers free shipping sitewide with no minimum required via coupon code "FREESHIP". That's tied with our January mention as one of the best sitewide shipping discount we've seen from Pottery Barn in recent months. Sales tax is added where applicable. Some exclusions apply, such as furniture and rugs.
Of note, the same shipping discount is available at PBTeen via coupon code "SPRINGFS".
