Once Upon a Child is a great idea - buy and sell gently used baby and teen clothing and toys. Since most kids grow so quickly, the possiblities are endless. It is a great place to browse around to find some great bargains - the prices are quite low. The toys are very nice too and you can find some new-looking toys there for great prices. You can also bring in clothing and toys to sell. They typically seem to offer about $2 per item which is not bad.
