Help! The neighbors have invited us to join their yard sale ... we have a lot of children's stuff we no longer need. High chairs, strollers, the usual pile if baby stuff we no longer need. Most of it is nearly new, and shows little sign of wear. So ... What's a fair price, compared to the price of new? Can any yard sale pros help us put a fair price on this stuff? I'm just looking for a rule of thumb, like 1/2 the price of new, or 1/3 the price of new, or whatever. Thanks!
