Maybe someone clued the seller in but I think they probably got 20+ e-mails and that raised a red flag as to what they could really get out the glasses. It's happened to me several times. I had a pair of Romeos listed fairly close to me, 1.5 hours, for $250 and by the time I made the final deal I paid $600 for them. It was still a good deal to me. The lady said she got flooded with e-mails and she just stopped responding to them all but knew she could get more money for them.
Guy by me is selling a pair o titanium finish Penny's for 185 w/box coin and papers. But his pics and sku are that of a XS. Either way I'm annoyed he won't text me back.
