I don't know how much it costs at Petsmart or Petco for Nutro but I know I get my brand from Amazon for cheaper with subscribe and save. I have it delivered every 6 weeks and save 20%. My pugs are on Avoderm which is the only food one of my picky pugs will eat and it also comes in small kibble size so my food addicted pug doesn't choke when she inhales it. It isn't a cheap brand however but keeps their coats and skin nice and soft.
