Some people think not but try thinking about it this way, If it is true that maybe as high as twenty percent of surfers use something to make their experience easier then you are annoying a large group of customers if they cannot even read your site.

Even if people with disabilities could not use your products I will take a swinging guess that they occasionally buy things for other people that do not share their disability. Does your product ever get bought as a gift? Can you see circumstances whereby a family member or company team member might wish to order your product for someone else for any other reason? If the answer to either of these questions is yes then you need an accessible website.
