Really good points. I fully believe in treating others the same way you'd want to be treated. I really hate websites that stack similar colors text on top of each other, low contrast. I never been tested professionally, but one of those quiz things online say I'm colored blind "mild protan".
I went to their website and ran Wave. It looks like from a few pages I sampled most of it is just adding alt-tags. So seems like a single or two developers with the right tools and testing could fix their website page by page over a couple of months probably. A huge store chain shouldn't be a problem to afford unlike a small tiny startup.
