The Fromm I get from petflow is $59.99 for the 26lb of Grain Free Beef Fritatta. I know the non-grain free formulas are cheaper, and I am certain the puppy food is not in the 4 star line so it will be quite a bit cheaper. If you do decide to switch, do it very slowly. It probably won't be as bad on his system as going from Nutro to AvoDerm, that is the hardest when going from a really bad food to a good food- so the transition should not be as bad.
Also compare prices with petflow, many have reported better prices at petflow then getting it locally, plus free shipping on orders over $59 (use coupon code EnglishBulldog) plus you do not pay any sales tax. Oh wait, you live in NJ --- You may have to pay sales tax.
