Hi Veronica. What a great idea so hand out samples. People need to know about this!
Hope you are blogging about your samples. If you don't have a blog then use iCraft's! Members blog about their shops, tutorials, and other things.
Here is the blog:
https://icraftgifts.com/blog/ And you access it in your account page.
A little secret is that many of us RSS the iCraft blog to our Facebook and twitter accounts for added exposure for the post.
Also, I would sell small samples - maybe 2-4 scents in a package. I think people would like that to try them or give them away as gifts. Just a thought!
Welcome and best wishes for your shop.
