It is a compromise between fuzzies v. utilons because I am unable to purchase them separately along with some other constraints. If the money goes to a charity I get more fuzzies, and given that whoever would do this would likely pick a charity that I consider to be a worthwhile charity (given the general framework of LW) there's a high chance that it will produce heavy utilons. I also don't have that much money so I can convince myself to part with more if I know that it is going to a charity rather than going to someone's personal use.
