I order Chicken soup for my Earl which does not contain preservatives or food coloring and I buy from www.petfooddirect.com
, whose shipping is very reasonable.
The price for the food is also very reasonable, I paid about $20 for an 18 lb bag of dry food, shipping was $7.99 I think, very reasonable for 18 lbs. but I do live in the same state as the warehouse, so it may be a dollar or two more depending on where you live.
I paid $17.99 for a case of 24 5.5oz cans with a shipping charge of $6.99.
Buy bulk, it will save you money in the long run!
