My family members are as well versed in the differences between brands, so they are spending the same kind of money. Anybody else, I'll tell them to read up on what's in the cheaper stuff. I've convinced a few coworkers to make a switch for the better.
People around here just think I'm an idiot. My favorite one ever "its the same thing..you're just paying an extra 35 dollars for a shiny bag and a name" OH REALLY NOW? everyone seems to feed their dogs the WORST food out here. Kibbles and bits, pedigree, Purina, etc.
