I have always bought extra on sale so that we wouldn't run out of something and have to make an extra trip to buy more. It was a combination of saving money and time, but on a small scale.
Now I'm wondering if I should make more of an effort to use more coupons with sales and really stock up on the things that we will need. I have done some reading about this and have to chuckle at the lengths some people go to to have a years supply of toilet paper, etc.
Do you stock up on lots of things? Are these things practically free and is that your motivation? How do you store these items?
