" You apparently don't care if you are wasting your time with mislabeled poses" 

Yeah, that's probably true. Since I don't use Poser more than a couple of times a week, a couple of minutes here and there aren't a big deal to me. I'm not sure we're talking about the same thing though and I probably stated it badly.

If the product didn't state that the morphs were required, you have every right to be annoyed and demand a refund. OTOH, if it said requires Morphs++ and you went soley by the filenames, that seems a little like seeing "battery powered" and not looking at the "batteries not included." My point is that I'm not overly concerned with the specific technology used to implement the product. If it says Morphs++ (which seems to be required 90+% of the time), then I'll discover quickly enough how to get it working. 

The stores can and should enforce some standards for commercial products.  I think that they're the only ones who could achieve what you want - if you can get them to agree.
