Whoa. Family of 3. $100 per week. 80% TJ, 20% mix of wegmans/Safeway/giant/whole foods (we live near all 5). Another $100 for the target trip (home supplies) and $100 Asian store. Not super big meat eaters (sometimes frozen fish, whole chickens, ground meats/deli). But we never budget, the low meat content and high veggie/fruit content keeps costs naturally in control.
