CVS glitch

So... thoughts about what's happening with CVS? I saw some momma's posting about the glitch and getting huge discounts on canvas prints but decided against because I feared something like this happening, and now THOUSANDS of women are pissed. Seriously, check the comments on the CVS Facebook page. So what are your thoughts? Should the company honor their mistake or are they in the right for cancelling orders when people knowingly took advantage of a glitch?
