Saving Money Without Coupons Par IV

Here are my final 2 big tips on saving money on groceries without clipping coupons.

• Meal Plan
  I know, I know. You're probably sick of hearing this one, but it really does work. My meal plan is based on three things. 1) What's on hand. 2) What's on sale. 3) What's in season.
  
  We shop once a week in order to take advantage of that week's big sales (like BOGO deals). I make my plan on Friday morning, so I can do my shopping on Friday afternoon or Saturday morning. I browse the ads of my local grocery stores, and check my pantries, freezer and fridge. I see what needs to get used up and build meals around those things. This week, I noticed that I have apples that are getting old (something very rare in our house of fruit-lovers), so I've planned to make stewed apples with the pork chops I have planned for Tuesday night. I've also planned to add them to the baked oatmeal I'm making for Saturday's breakfast.
  
• Not buy
  This one is the hardest for me. I grew up with my Depression-era grandparents. I was taught to always stock up on food, because you never know. I've had to learn some self-control. If something isn't in the budget, no matter how good a deal, it isn't in the budget. Period. If it's that important, I need to put something else back.

I still use coupons and take advantage of sales, but they're no longer my most important means of keeping in my budget. What are your favorite ways to save money on groceries?
