aren't you saving a good amount of money too though. I don't know if you and your partner drive to work, but I'm saving about $120/month just on gas, and I'd probably end up saving another $100-200/month on vehicle depreciation and insurance if this went on indefinitely. an extra $300/month makes a big difference in the rental market where I live.
I normally commute by bike so this isn't a factor for me. I'm also using more electricity, and I'm drinking the coffee I bought rather than the office coffee.
ah okay, so you don't save anything on the commute. I'm happy to pay for my own coffee (I get much nicer beans than we have at the office), but I have noticed that my utilities bill is no lower than it was mid-winter.
