Anyone have any yard sale tips? Next month, I'll be participating in a multi-family yard sale and none of us have ever done one. I'm looking for general advice and have a few specific questions to start with. 1) How much cash (and in what denominations) should we have on hand to make change? 2) How should we keep track of whose stuff is whose? We thought of assigning everyone a color and putting color stickers (separate from the price tag stickers) on all the items, so we know who it belongs to. But what if customers switch stickers? Will they do that just to be obnoxious? We figured they might try to switch price stickers so having separate color stickers might at least maintain some identity of the items. 3) The kids want to help out. They are mostly in the 5 and 6 year old age group. What can we have them do? Lemonade stand? Any comments are appreciated!
