WFMW: Buying fewer trash bags

I got tired of buying tall kitchen bags so often. Now, during every meal prep, I hang a plastic grocery store sack on the knob by my sink and use it until the meal is over. Then I trash it, full or not, at the end of the meal.

I used to take the tall trash bag out nearly every day but now it's about every third day. This little tip has really cut down on how often I buy the "real" trash bags.

One thing: I sometimes make them "paper only" bags, so if there's a hole in the bottom then I don't have to worry about leakage. It is surprising how much paper a family of four can collect in one day!
