Saving money on groceries!

I was so sleepy after working 2 12 hr. shifts that I went to bed around 9pm last night. I could hardly stay awake. Of course that meant I was up at 5:45am.  I am also fighting allergies/cold/ or sinus infection. Not 100% sure which.  I woke up stopped up yesterday morning and my head was clogged all day. I  took a Claritin this morning and I am starting to feel slightly better.  Natalie was having a leftover "I didn't drink enough water" camp stomach ache and was lying on the couch alternating between moaning and sleeping before church, so we decided to stay home.
Actually, we took advantage of the no tax on school supplies and went to Wal-Mart to get her something to help her stomach get back to normal and I went ahead and spent my $50 I had budgeted for school supplies this week. I hope I got enough for the whole year.  You can get a lot of school supplies for $50.  Walmart is pretty empty on Sunday mornings.
Not much else planned for today other than church tonight and the older girls have a devotional afterward.  Hoping my head will clear up enough to do my exercises.
I also wrote the checks for the rest of the bills due in this 2 week budget.  Since Aaron got paid yesterday.  Looking at the bright side, I have enjoyed this challenge of staying in the budget.  I am such a nerd.
I am spending SOOOOO much less money on groceries. I don't even know how much I was spending before, but I am know that I am saving at least $200 a month, possibly up to $400 a month.  .
This is by making a detailed menu of 7 dinners and desserts, making a detailed grocery list from this menu, adding breakfasts and Aaron's lunches to the grocery list, shopping at Aldi and only getting what is on the list.  I make the "hard" dishes on the days I am home.  Normally, I would buy a lot of premade, processed food, easy to make for Aaron while I am at work. I save the easy dishes and leftovers for Aaron to make or cook. He can follow any recipe if he wanted, but his goal is easy and the least amt of time in the kitchen. I love to cook, so it works out good that way for us. I also take all leftovers for my lunches at work.  I have to take a lot, since I leave the house at 6am and arrive home at 8pm at the earliest. Even eating in the cafeteria at work at a discounted employee price adds up.
Aaron went to Aldi with me Friday.  He was amazed that the full grocery cart was only $151.  I am too lazy to do a price comparison, but guess that I probably save about $50 shopping there when I fill up the cart. The bad thing about Aldi is that they don't carry everything.  For example, rice milk, I have to go elsewhere.
