I wouldn't bother returning them if what you say happens to be true... There are plenty of toy drives in my area that could use Marvel Legends...
You sound like a good man. It is really stupid though with all these variants or running changes. You think that once the store has these in hand they could at least post the correct figure and description of what your getting.
I am okay with variants since it keeps the spirit of the hunt alive but "running changes" is the worst idea ever...
