1) Wise Stamp email signature. Drive buyers to your shop just by your email signature. Make sure you are using Gmail, Yahoo mail, Aol or Hotmail for your email. I have another email so I can't use this one but it looks nice, clean and professional.
3) For Bloggers, use this simple HTML code generator to easily add Treasuries to your blog. I use the "tiny" size to fit inside my Blogger blog.
4) If you like to use a white background for your photos FotoFuze will give you a true white background and really make your product pop!
I am always looking for cool tools; if you know of any others please share them here!
