So you parse your credit card statements (or equivalent) for the coffee & travel costs? I thought the travel was by distance (not cost) at first, which is what I was curious about because it would require a more active role in logging on your part.

Is this purely for kicks, or are you trying to use it to drive behavioral changes (e.g. spend less on coffee)? I ask because I always think about doing this, but I get a stuck on the "why".
