Enter a search string to search the shopping cart catalog for items whose names or descriptions match that string. Only exact string matches will be reported and the search is case-insensitive. Once the matched items are listed, you will be given an option to add them to your shopping cart. For example, typing in "cd" (without all the quotes) will list all CD products, and typing in "shirt" will list all the shirt products. Entering a blank form will list all the items in the catalog.
