A ton, I'm sure. We're still in the beginning stages of becoming Mustachian. We've already made a lot of big changes (selling car, paying down a lot of debt, etc.), but we could definitely do more. I look at it as a process, though...we've stopped eating out so much, and to achieve that I set our grocery budget at a very un-Mustachian $600/month in Aug. and Sept, then $500/month for Oct., next month is $450/month, and so on. Plus we're continuing to pay down debt, and that alone will free up close to $500/month when we're fully debt free.
Next up is renting a much cheaper place when our lease ends in May. (And in the meantime, getting rid of a ton of stuff so we'll fit into a 1 bedroom.) We currently rent a tiny rowhouse for $1725/month + all utilities, and we could switch to a 1 bedroom apartment for probably $1200-1300/month, or even less if we move to a less convenient part of the city. (Not sure if I'm up for that yet, but we'll see what apartments are out there when our lease is up.) Water and sometimes even heat are included in the rent for apartments here, so cheaper housing alone would save us $600+ a month. That's our next big low-hanging fruit for sure, aside from becoming debt-free.
