Which would be more beneficial to you? Us ordering copies directly from you to have them mailed to us, or us going to B&N and buying a copy off the rack? I would assume the later, as it would help prove to your distributors that they're worth the rack space, but I frequently assume wrong.
Anything that helps us do our job better with less red tape and guaranteed income stream will help the magazine run smoothly. Buying direct would be the most 'beneficial to me', but to Bitcoin as a whole, I would imagine so long as we are just selling through the mail only, we are doing little to nothing that a website couldn't do as well, agreed?
The issue here is then-- how can we make sure our magazine is seen in every major shop in town? The tough answer is 'to sell enough copies to make it worth everyone's while'. That means we have to fight to win the community over and gain it's support before we can truly take on the mainstream, or as I have mentioned before we would become "nobodies in both places".
Know that we are taking every logical risk to get our issues out there into stores, but too much too soon will bleed us to death.
