$15 for 7lb of Blue Spa is actually pretty good price. Over here, it costs about $20, and Evo is even more expensive, about $25 for 6 lb. If you are concerned with the price, premium food shouldn't be the place to look for value. It is inherent in the definition of premium brand that it is bad value for the money. Generally, the cheapest low profile food is the best value for the money, simply because it has no built-in brand name premium and has very little added cost such as heavy handed promotion and commercials, etc.
Even cats fed the lowest quality food are living like a king by animal standard, you shouldn't feel so bad about feeding them cheaper food.
