I need Royal Canin Early Cardiac Dog Food. The cheapest I found was for a 17.6# bag for $50.29 at petfooddirect.com. If I purchase over $59 then I get free shipping so I would just get 2 bags at once. This comes out to a total of 35.2# for $100.58 at about $2.86/pound. Anybody know of a place I can get for cheaper than this per pound? I don't mind buying in bulk to save money. I have an Rx for it too if the website requires one. Thanks!
