You've learned how to find the hidden treasures. But you don't find every treasure you need at one department store. Gather several large stores together and you have a mall. You park your car once and you explore each store, buying some items from one and others from another. The malls of the Web are its universal search forms.
Some folks avoid the malls, enjoying the luxury of personal shoppers.
Meta-search forms are like personal shoppers. But on the Web, they work for free, offering the maximum level of convenience. They spend a lot of time thinking about shopping. EZ-Find at the River is one such service. They are labor-saving devices.
