I never have. I just place orders. Failure to respond to emails seems to be common among a lot of retailers. Companies I have sent emails too rarely get back to me and when they do, it's months later when I forgot why I sent them an email in the first place. I ask about a hand guard on one site a while back and it was probably four months later I get a message back stating they do not have access to one. I'm wondering one what. Did eventually figure it out.
