question:
Delivered by UPS, this product is just about perfect.  It does not have a disagreeable smell and the dogs love it.  It is much less expensive than prescription dogfood and our dogs are thriving on it.  You can even see an occasional pea and/or carrot. No grain to worry about.

question:
I was really impressed with this.  There are many flavors, and quite a bit of heat.  With this and your favorite brand of cocunut milk you can make some great Thai curries at home.

question:
This is twice as expensive as basic box Mac and Cheese.  It is just so so in taste.  If you check the ingredients it is not much different than other Mac and Cheese.  The cost does not justify the ordering.  I will not be ordering from Amazon again.  The cost is much cheaper at a big box chain.
