Johnny, I totally understand your frustration. Just a little info from the customer perspective.

My husband and I are huge Avett Brothers fans. I collect their posters which are created by several fantastic artists posting on this site.

I am very adept at searching the internet, I make my living by track stuff down through various methods including computer/social networking information.

Just a few observations:
1. A simple google search will not pull artist stores up.
2. Ebay is convenient for people who don't have the time to do indepth digging for these posters (like I do).
3. I have had to join several sites such as gigposters so I can locate information on store sites then save them and search them all independently. This takes a lot of time!
4. Sometimes Ebay is the only place I can locate a poster that has been sold out.

I wish there was a way for y'all to band together and creat a meeting place type site that would then redirect people to your shops. It would make it so much easier. I personally respect the fact that artists are selling these posters at an affordable price so that fans like me can purchase posters of the bands we love. I do not purchase them to resell, these pieces are framed, hung on the wall and enjoyed.
