The second is to have everyone bring in their items already marked with a price.(We always tell them that if it doesn't sell they have to take it back home with them.) Put them out on a table and allow enough time for everyone to check out what is there. You cannot buy until a given time. Then you let everyone loose to grab the stuff like a yard sale. You have one or two cashiers to take the money. If stuff is left after the first round, you cut the price in half to see if you have more takers.
