I wish I could remember where I read this tip, so I could properly credit it. If you originally wrote about this on your blog, please let me know so I can link you.
Anyway, to stretch your laundry detergent a bit further, when it is nearly empty, add some vinegar, shake up the bottle and then pour in your wash. It will wash just fine and will get the tiny little bit of laundry detergent that is left out of the bottle. Waste not want not!
