What happened to Lego Batman sets that have made them so coveted and expensive? I purchased everything up until they released the Harley Quinn set. It seemed like TRU always had them on their shelves and then one day, POOF....nothing! Did the liscense expire without notice? Was there a problem that anyone ever heard of? It's just strange that these sets, being as recent as they are, are at such inflated prices from what they were originally sold for.
