I don’t use web sites that don’t offer a web site search.
When I'm looking to order something online I want to be able to do a site search to find exactly what I'm looking for. I don't have the patience to look at a company that doesn't offer site search. I don't want to look at everything they have, I want to do a web site search to find what I need right away. If you can use a search tool you can see everything in just the category you're looking for. If the company doesn't have a search tool you have to look at every single thing. If you can do a site search you can cross of potential providers quickly. In this day and age everyone should offer web site search.
