Keeping a webpage up with your contact information, pricing, and information on how you operate is also a benefit to the customer. A quick web search will pull up a lot of the information the customer needs and they don't have to find time to call you. Websites operate for you 24 hours a day and 7 days a week. So most of the calls that you would receive about operating hours and other quick questions could be looked up on your site and provided to the customer while you are at home with your family. It can also provide business to you in this way, because your competitor likely has their store hours and prices online so the customer doesn't have to wait for you to open so they can call and ask.
