I used to be able to buy TOTW (before they were bought out by Diamond) for around $40 for the 30lb bag. After they got bought, the prices creeped up and they average @$55 now.
I just looked at NutriSource because I had to buy more food for Molly. I've been rotating various non-beef formulas of Orijen and Acana for a while now and while I'm happy with all of the formulas we have tried so far, I also wanted to look at a grain-free and potato-free food for her to see how she does. The pet store I went to recommended NutriSource and I looked at the label and it seems like a reasonable food and while I didn't look at the price, the guy said it was pretty cheap compared to Orijen/Acana.
I didn't buy it because I wanted to look up who manufactures this food and it is by a company called Tuffy's Pet Foods - they only make pet food and only at their own plant in Minnesota. http://www.tuffyspetfoods.com/viewimage ... 14&catid=5
Their Tuffy's line of products look pretty scary (corn, wheat middlings, corn syrup) but the NutriSource doesn't look too bad. Just consider though that while this might be a smaller company, they still have multiple "house" brands.
At this point, if it is hard for me to find out information about where/what else a company manufactures, I will be less inclined to try the food out. Actually, that's one of the reasons I started getting TOTW before because they were a smaller company. While problems from a small company are less likely to get noticed, there is also a higher chance of cross contamination across multiple brands with larger manufacturers/plants and salmonella isn't the only thing to worry about.
