Our spending is fluctuating while we tweak it so that we get the healthiest food for the best possible price.
That being said--we shop at Wild Oats (a natural food market) and Wal-Mart.
We have been on the south beach diet for over a month. So no pasta nights for us! We eat only whole grains, no added sugar, and fresh fruit and I eat chicken and hubby eats the allowable cuts of red meat (I don't eat red meat, so I don't know a ribeye from ground beef

)We do frozen veggies, and try to get things in there most natural format (meaning no added anything if possible). So it makes shopping inexpensively a bit complicated--though we are trying to make it as cheap as possible. I have stopped purchasing pre-packaged lettuce and that has helped cut cost.
I do evenutally want to try making my own bread and maybe that will reduce costs.
The chicken I buy is free range and just chicken breast meat. Unfortunately it is only sold skinless and boneless--so I have no choice to purchase non-prepped chicken breast. The whole grain items such as bread--I shop for no added sugars such as corn syrup and such. Hubby settles for rye bread as it is allowed on the diet we are on--and he wouldn't care if it was processed in a salami factory--so I am searching for the cheapest version with seeds that I can find. We steer clear of additives and preservatives and dyes as much as we can which unfortunately spikes the price of food. We also only buy organic milk & yogurt (everthing else is conventional). Thank goodness, our store (Wild OatS) has one of those coupon printing machines like they have at regular grocery stores, so I am able to do coupons. At least I can save some money.
Diapers--we do an off-brand as we do wipes. We purchase these items and other items at Super Wal-mart--if it meets the above criteria, we buy it at super wal-mart--otherwise we buy it at Wild Oats. Cleaning supplies and stuff--best deal we can find at Wal-mart.
I am trying to get the spending way below $200 per week inclusive of baby necessities and household non-food items. As hubby wants the budget to remain at $800 per month. Wal-mart will be new for us--it isn't as convenient as the other local stores--but we are hoping that saving money there will balance with our other purchases.
I will know as soon as we plug in the receipts what the final tally is for the month in comparison with the month of July. If you add up all the eating out and plethora of grocery trips--we were over $1200 last month.
As of a few days ago, for this month, we were over $300 less than previous months expenditures--but I have been shopping for more groceries. I think we will definitely be less--but not that optimistacally as of yet. Trying so hard to only go ONCE per week and eating what we have! And STICK to only what is on my grocery list.
