Um, who knows?
I was in the payment process and noticed that there was no yellow lock on the page, so I erased my info and asked them about their security. It took them a WEEK to get back to me and then they were irritated with me for even asking. During that week, I made a comment in the contact us column about the lack of security and they immediately deleted it and emailed me saying they couldn't have people just bashing their site. The problem was resolved in time (I was using a Firefox browser) and they gave me a $10 credit, but I continue to be reluctant to buy from them, simply because they admittedly delete ALL negative customer comments from their site. Maybe I'll buy from them someday, but there are so many other sites that offer the same type of stuff.
