For the candy cane and elegance, theres not much you can do as the sizes are listed. You can argue that you thought it was 5" elegance skeleton but he can just as easily say the polyps. However the gorg ( which you're happy with ) and the frogspawn have photos without any indication that you're not getting exactly that piece ( no frag size or polyp #, etc ) so its a reasonable assumption that you're getting those exact pieces. Based on that, I would call the store, since they advertise as affiliated with that seller. If they cannot resolve it satisfactorily, then file a dispute with paypal, credit card and ebay. Then leave a negative feedback as a last resort.
