I didn't see Zibbet or Trendy Indie mentioned.
I have recently dropped my Trendy Indie shop due to spending so much time running two other online shops PLUS doing local shows. but I'm really stuffing my Zibbet shop full of Naughty Bits and Melted Media.
Awhile back I had purchased ad space here on Craftster and had run a promotion for Zibbet and got so many people to sign up that I can list as many items as I want and make all the sales I can ABSOLUTELY FREE! FOREVER!
You can do this too (though not necessarily on the grand scale I did). Just sign up on Zibbet.com and refer 7 other people who sign up. The flat monthly rate will drop by $1 for each person who you get to sign up. It's so easy, and the site is awesome. Come check it out http://zibbet.com/
