My office potlucks are obscenely wonderful in the quantity, variety and quality of food. I usually splurge on the dish I bring because I know other participants will do the same, but over the past year I've noticed (because of the rising food prices) my potluck dishes are getting more and more expensive. I've also noticed fewer people are attending than in the past and wonder if it is too costly (or too ambitious) for them to participate. I was wondering what other people's experiences are. Do you set a limit on how much to spend? Do you budget ahead of time? Have you cut back on how many you go to? Do you share the costs with a friend or friends? It is an odd topic to be curious about, but for some reason I am.
