Believe it or not I thought of a couple more.
25. If you do use the dryer and you use fabric softener sheets, cut them in 1/2. You want be able to tell the difference.
26. Cut back on laundry detergent. If you fill your washer with nothing but water and let it agitate for 5 minutes and there are bubbles, you are using too much detergent. I usually use 1/2 of what is suggested. The same for liquid fabric softener.
27. Make a menu for the week and stick to it. I try to include every thing that we will eat. Breakfast, lunch, dinner and even snacks. If they are planned ahead of time you make less trips to the store and really do tend to stick to the menu. You can be a little flexible after the menu is made. Maybe on Wednesday you decide to cook what ever you planned to cook on Thursday, just make sure you cook on Thursday what you were going to cook on Wednesday. If you plan to eat out one night, put that on the menu too.
28. Make your shopping list after the menu is made. Check to see what you have in the pantry before you make the list so that you can use what you have on hand first. Then only buy the things you need.
