For new customers only, Wag.com
(a sister site of Diapers.com and Soap.com) takes 30% off
one item via coupon code "THIRTYWAG". (A maximum discount of $20 applies.) That's tied with our January mention as the best percent-off coupon we've seen from this merchant, which sells pet food and supplies. Shipping adds $4.99
, but orders over $49 (prior to discount) receive free shipping. Some exclusions apply.
