Buy, sell, buy, sell. Teach your little one early and who knows — will she be the next Wall Street genius? At least you can offer an early lesson in money handling at the Hawaii Children's Discovery Center's Keiki Swap Meet, from 10 a.m. to 1 p.m. today at Kaka'ako Gateway Park.

Kids will be responsible for collecting, pricing and selling their goodies. Other folks — that's you buyers — can come along and support the keiki and maybe find some treasures among the stock.

There's a $3 registration fee for each seller; buyers enter for free. 524-5437.
