Looking at your items they seem quite expensive to me.  If you think they are worth than then fine but obviously I have no idea what they are worth. LoL

One other thing is the descriptions.  You need to make then more interesting and put information in them.  I noticed one listing that has four glasses in the pic but the listing title says set of six.  You may need to fix this.

Other than that you may just have to be patient.
