This is a great question. We are still trying to figure this out right now. Our vision is to be a service that handles everything - and that means everything from ordering food, to ordering clothes, to booking a one week's vacation in St. Thomas. The fees obvioulsy vary. Any ideas you have about doing this in a more straightforward way would be welcome. For now what we are doing is thinking about what would be reasonable on the fly. Sometimes it's more than people think, i.e. if someone wants milk delivered to their house in Wisconsin, we have to call a local courier, etc. However we've found people are willing to pay more than you would think, too.
