I buy Canidae from
www.petfooddirect.com -- they have provided good service and the price is not bad -- I always use a coupon code. There are usually some online and after you order they will start sending them to you email. I now get 20% off. Canidae is on sale on their website right now too. I just ordered a resupply. You can also go on automatic delivery and never have to worry about running out. I have not done that yet, but may the next time.
