sourceforge garage sale shopping carts?

Are there any shopping carts at Sourceforge that you would recommend? Or other Open Source script? I don't mean to be cheap, just find a fast solution for a friend. Something simple, a simple garage sale with a few options and categories. I created the shopping cart for www.compcanlit.ca, and would not have the time to recreate another. I'm always happy to share code, especially if that one suits someone. John www.jtjohnston.ca
