I'm a big fan in principle of spending money to save time, but I've only recently started to really search for new ways to do it. I think the Forum community in aggregate probably has a lot of great ways to buy time that I haven't thought of yet, and I'm keen to collect new ideas.
What are some ways you buy time that you think are particularly effective? What are some ways you buy time that you think other Forum users might not have thought of?
I'm especially interested in interventions you've tried and found valuable that are a bit wacky/out-there.
