shopping without a net

or worse a shopping list...
In an effort to be more budget minded I generally do not go into a grocery store without a very specific list of what we need, even if it's just for milk & bread. This seem to have helped cut down on my wandering up & down aisle buying things we really do not need and spending $50 on a shopping trip that should have run $10. Yesterday evening I was out & about and knew I needed specific groceries for tonight's dinner so I stopped and brazenly decided what the hell I can accomplish the weekly shop and be done with it all. I did very well planning meals in my head and making sure I bought only what we needed. I was oh so proud of myself until this morning when I realized that I was lacking 3 items necessary for today's menu. Today's menu you know the only reason I had gone shopping in the first place.
