I don`t like to lose the parent site. Open in a new window is my preference.
Hi Karen -
Welcome aboard from a fellow Southern Californian.
I also prefer that links open in a new window. But there`s an even more important reason to set up your links this way. In an e-commerce business such as yours, you don`t want to send potential customers away from your site - you want them to be back at your site when they close the link.
