Totally not ridiculous...for a family of 6 (with teen/tween/boy eaters), I spend about the same amount ($1200/month), and I don't live in Southern CA. That breaks down into a weekly grocery shopping trip of between $180-$200, an extra Aldi's trip every month for about $75,
Amazon subscribe and save and Staples orders for K-Cups, toiletries, and single serve snacks/meals (for spouse's lunch) of about $100/month, Target runs for pet supplies and other household needs of $100/month, and about $30/week for my husband to stop on the way home from the gym and pick up milk, chocolate milk, or a needed item for a dinner (or his beer making supplies if we don't need anything extra that week).
Yes, I don't break down food vs pet supplies vs toiletries vs household needs...it's all part of the grocery/store shopping...
Looking at this week's receipt, we buy a TON of produce (only organic if it's the same price or cheaper) and eat a ton of produce...and really eat a ton in general b/c kids who are active eat! Last week's receipt, I bought 5 lbs of gala apples, 4.5 lbs of reduced price bananas (all green and just yellow b/c apparently people ripped off singles), 4 lbs of D'Anjou pears, 3 lbs of strawberries, 3.5 lbs of red grapes, 1 20oz Asian cabbage/lettuce/carrot salad bag w/ dressing and toppings, 2 lbs of organic broccoli (it was cheaper), 1 large container of organic baby lettuce (cheaper), 2lbs of baby carrots, and 3lbs of sweet onions to add to my only leftover produce of russet potatoes, sweet potatoes, a small container of fresh pineapple (that I cut - we're 3/4 of the way done), 1 bell pepper, and 1/2 an English cucumber...I should be able to make it to my next real trip with about the same amount left, but no days where mother hubbard's cupboard is totally bare...my garden herbs are the only produce I grow, so I can't save by growing any of what we eat

...
But to be fair to the grocery budget, I have to include our "eat out budget" b/c if someone gets school lunch/work lunch every day or eats out every meal of the weekend, they will have a low grocery bill, but a high eat out bill. We budget $60/week for one meal out for the family - every other meal for everyone is eaten in or brought in...sometimes we are under (our favorite lunch sushi buffet always comes to $51 w/ tax/tip already included and pizza ordered in is only $25) and sometimes we are over (our Easter meal was $106 w/ tax/tip/Groupon cost already included)...but we tend to be about $250/month. With such a low eat out budget, our overall "disposables" budget (it's how I differ from shoes/clothes shopping) is $1450 and I think it's pretty close to a minimum healthy budget. Could it be a little cheaper - sure, I could give up coffee and K cups...but then I'd be miserable and probably buying the coffee out, wasting the savings. My dad said everything in moderation...and I keep to that mantra (except maybe in produce, b/c I love to eat and cook fresh over frozen or canned)...
