PetFoodDirect.com is taking 17% off sitewide with no minimum purchase via coupon code LABOR17 through Labor Day Weekend. Plus, this stacks with their Labor Day Sale, where items are reduced up to 40% off. Combined, that's the best discount we've seen from them in months. Shipping starts around $6 (but can be higher for heavy items like dog food and cat litter). Sales tax is not charged in most states. Some items such as prescriptions are excluded.
