One tip, is to keep re-using them as long as you can. We have non-biodegradable trashcan liners for our kitchen trash-can. It helps that we recycle, compost, and are vegan (so nothing particularly icky is in the trash). We can usually go 2-3 months on a single kitchen trash bag, they usually give out because the corners wear out and start to tear.
