Wag.com is a new site for pet products by the people behind Diapers.com and Soap.com. You can get 20% off your first order by entering promo code WAG20, or you can enter code CouponMav to save 10% your first order and have $10 donated to the American Red Cross. They already have pretty darn low prices on a lot of items so 20% off is pretty sweet! Don't forget that you can mail in manufacturer coupons and that they offer eCoupons on selected items. They also offer free shipping on orders of $49 or more (including those really heavy bags of dog food). You can really stack the savings up if you are savvy!
