I just thought of what you need to develop next
However you might need a much bigger piggy bank. What I am about to say is not meant as a joke.
You need a scratch and sniff for your site. How are we suppose to know what Pikake Perfume smells like?
You know how they put those samples in the magazines, what about doing a sign up here for Free samples?
You then could snail mail a scratch and sniff card and you have also collected another way to reach buyers.
I really hope you don't think this is a dumb idea but it would take extra funds.
