Pinching pennies

I've done a lot of searching on ways to save on my grocery bill in the last year. One of the things I have found is that cutting the cost of drug store items has saved me more than anything. I gave up my shampoo and began using the same one mom and Cindy use. Though my hair is far more oily than theirs, I can just wash it more often and only wash it once each time and get the same clean hair and don't use any more shampoo. I just wash it in the sink every other day (if I shower everyday, my skin drys out way too badly).
I've found if I make my own foaming facial cleanser I save a few pennies and I don't waste as much cleanser. I found this article quite a while ago, but didn't put it to use until 3 months ago. I used advice I got here. While this article is about hand soap I use it to make my own foaming facial cleanser using a cheap store brand general facial cleaner. In fact this Walgreen's cleanser, it's a gel style cleanser and hard to rinse off and I end up using to much. Now that it's foaming I use far less and get the same clean face. I've been using it for about 3months now and I just opened my second bottle of Walgreen's cleanser last week.
I use about about a tbsp. of the Walgreen's cleanser in the 6 oz bottle I recycled. Since I wash my face no less than 10 times a day (extremely oily) this has kept my skin from drying out and saved me tons of $$$.
I also recycled an old liquid hand soap bottle and put my dish washing soap in it. Now a few pumps of soap keeps me from using to much for a sink full of dishes.
I've started scrubbing out the sinks with baking soda and I keep a spray bottle filled with 50/50 blend of water and vinegar by the sink. I give it a spray down every time I use the sink, this cuts down on cleaning products. The vinegar water is the perfect cleaner for the fridge too!
These are just a few of the things I been doing to cut the grocery bill, what are some things you do that helps cut that every higher total at the check out stand?
