I don't see how a "we" can do $150 to $250 a month shopping at one store getting delivery if that also includes toiletries.
Some things have a base price. Fruit is $0.60 to $0.80 a pound everywhere. Figure eating 1 pound a day for 2 people that is near $20 right there. Even 1 ply toilet paper made from recycled diapers would be $10 a month.
I don't doubt your figures but I would love to see a typical breakdown of your meals and food, if you have the time and are willing to share. It might give us some ideas where to save.
I'll provide a breakdown...but I worry the nutrition police are going to face punch me about my sweets.
Our major protein sources are eggs, black beans, and chicken breasts.
Our habits are inconsistent, which is why our grocery bill fluctuates. Right now, we're eating hard boiled eggs as a snack. We buy eggs in a package of 5 dozen for $8.84. I eat 2-4 eggs/day. We spend about $20/month on chicken breasts ($1.99/pound). I stretch the chicken by using it as a component in a dish rather than the main course. My favorite recipe is chicken taco bowl from Budget Bytes (
http://www.budgetbytes.com/2011/07/taco-chicken-bowls/). I double the recipe for everything except the black beans and corn. I use a 'Rotel-esque' can of tomatoes instead of salsa. We eat chicken taco bowl on chips, in tortillas, and mixed with eggs. I'm usually lazy and use cans of black beans ($0.68) instead of cooking our own ($2/2 pound).
For carbs, I love sweet potatoes. I buy about 5 pounds/month. We also eat a whole wheat pasta dish at least once/week. I'll make a pesto (basil $2 plant from TJ on our balcony, minced garlic bought in a large jar, olive oil) or defrost a marinara sauce (
http://www.budgetbytes.com/2011/11/slow-cooker-marinara/). We also have egg noodles, which I use when I make chicken noodle soup.
We also buy several pounds of fruit every week. This week we have apples($1.40/lb) and bananas ($0.59/pound). We each 1-2 pieces of fruit/day.
For vegetables, we're even more inconsistent. We buy a lot of avocados (~$10-20/month). I buy a large clamshell of spring mix for salads (use whatever we have around for toppings) 2-3 times/month. I toss frozen peas in pasta and rice dishes. We're also buy baby carrots and hummus about 2x/month ($10).
On dairy...We also spend $20/month on cheese. No regrets. We don't buy shredded (it tastes weird to me, so we shred our own). We buy 1/2 gallon of organic milk ($3.58) every other week. I also buy a container of Fage 1x/month. My DH buys a few Yoplait yogurts every once in a while for snacks/breakfast.
Now for the bad stuff. Last week, I spend $2 on pudding mixes (4 boxes). I'm putting them in our popsicle maker. I also buy expensive dark chocolate (Ghiradelli >70%) frequently ($2-$4/bar). My DH drinks about 4L of diet orange pop/week (~$7/month). I've started to buy turkey bacon ($2.50/week) too often. We also buy a fair amount of alcohol. We drink ~2 times/week. Hard alcohol (~$5/month), wine ($20/month), beer ($5/month).
We don't drink coffee. I drink tea, but it's all gifted (so lucky).
