I found a great site today, thanks to a fellow artisian at Artfire. www.merchantcircle.com
You can link up with other local buisnesses, make cupons, and get more exposure all for free.
Of course there are options for other things which you can pay for, and their prices are very reasonable, but you can get plenty of exposure with the free listing if you take the time to set your listing up nicely.
You can upload pics of your work/studio, make cupons and have them advertised on other local businesses listings for free. It's really great - check out my listing to see what it looks like. http://www.merchantcircle.com/neighbor/972001
Just thought I'd share my findings - happy selling, and happy crocheting!
