I ordered from them 4 times over the years. I am not sure that I even got confirmation emails every time.
It has been more than several years since I ordered from them, but I never had any problems. I used the feedback form in the past and had quick responses. I received return responses from email, as well.
I do know of one guy who had problems with them when he ordered his second binder (I don't remember what the problem was, this was about 3 years ago), and I don't know how it got resolved.
I really think things will be ok. They certainly wouldn't be in business for this many years if they were inconsistent. Moreover, they are certainly not a scam.
