It's important to remember making websites more accessible often benefits everyone in some way. e.g. providing an alt text description for images on your website obviously benefits visually impaired users, but it also benefits people who can't afford high bandwidth or people who are moving through a remote area. In the Microsoft framework these three scenarios are called:
1) Permanent (Visually Impaired)
2) Temporary (Can't afford high bandwidth)
3) Situational (In a remote area)
There's good online resources for understanding these concepts [1,2,3].
Anyway, for companies as big as WinnDixie, with $10B in annual revenue, they should be designing their websites to be accessible by everyone. For small businesses it would be nice if website building providers like SquareSpace and Wix made this as easy as possible for their users.
