I generally use the "Ed@" address, but never had problems with the "Info@" either. I may be able to offer some of the reason. I spoke with Ed a couple of days ago about the down group buy for this year and told him I was getting a lot of early interest. He said that his September was very busy and asked if I could wait to start the group buy in October instead. He is probably out looking at rocks.
Always a price to pay. When working with cottage shops sometimes their real jobs, school, adventures, or their vacations get in the way of our gear addiction. It'll be worth the wait.
