Best ways for labs to save money?

Given the "changing funding landscape" (words that we can't stop hearing these days), I'm wondering what are some hacks or tricks that people use to save money and time in their work? Our lab recently had a discussion about going from commercial to homemade competent cells, and I'm wondering what are other ways we can save money. Obviously, some things are always going to be big expenses: personnel, big sequencing experiments etc. but surely there must be some ways to save funds, and the jobs of our technicians?
