The DogKennels.com free shipping offers only appear sporadically, but generally last several months and require a minimum purchase. When browsing items, look for the red "free shipping" text next beneath the price on each product page. DogKennels.com also has a tab on the left side of the homepage titled "quick shipping." These items ship within one day, usually for a flat $5 fee. To save even more, visit FreeShipping.org and browse the DogKennels.com free shipping page for codes that aren't advertised on the site, along with coupons and for a percentage off your entire order.
