I noted the same thing about what the OP is saying regarding toolsdelivered.comXX web site. At first my purchase would not work, then within a few days of that I'm getting warning msgs on my web browser about a potential security risk, and then no-reply to the emails I sent.
I've dealt with those people on a number of occasions and I don't have any complaints, the web site right now is non-functional based on what I see or can't see on my end, along with no follow-up on email communication.
I would like to continue doing business with these guys, I hope whatever they are doing or what is going on, gets resolved.
For now whatever is going on is unknown to me, but the end state is as of right now the web site is not working. Hopefully they did not get hacked or their web site compromised.
