I used to buy the quiz prizes myself in previous years, and depending on how the auction goes, I might do the same thing this year, so that we can have more tea/biscuits/sandwiches instead ;)

The auction's seperate from registrations, because we rely on registrations to pay for the room hire, which is the biggest of all the con expenses... we also keep the money for scholarships in a seperate pot, as that's donated for a distinct purpose.
