Dr. Harvey's Raw Paradigm, making raw more affordable...

I've been reading through old posts to this sub to get ideas on how to reduce the cost/make raw feeding less expensive. I currently feed commercial raw (nothing homemade) with some kibble for when I forget to thaw, but also to cut the cost. My two adult dogs (34 lbs and 18 lbs) currently eat about 80% raw and 20% kibble. My breeds actually NEED carbs and do better with some. I like to get the 25-lb. boxes of Northwest Naturals bars, which cost about $6.30 lb for the turkey, a little less for the beef.

I think my best best will be to get some ground or boneless meats on sale or at Costco, then add Dr. Harvey's Raw Paradigm...is there a better supplement you'd all recommend to round out and balance a raw diet that does NOT include bone?

I started feeding raw back in 2001 and used to do the whole "drag home 30 lbs of chicken necks from the butcher and parcel them out and freeze" thing, and I cannot do that again. I'm a vegetarian, it's disgusting, and neither of my dogs can eat chicken. I'm also a single mom so time is very limited. Other suggestions welcome!
