In retrospect - if you want to have buyers take advantage of you - get something for nothing and then YOU pay high postage and other fees with very little real ETSY traffic - go ahead and open one of these shops.
My sincere advice is take your money and dreams to another platform - Amazon, shopify and rubylane are more professional outfilts that value sellers just as much as their customers. I am soo angry with their absolutely obtuse dispute resolution... I can't put the words online.
I am sorry I started there and invested so much time and effort. Amazon is actively recruiting 'hand made sellers' and ETSY will soon realize the hard way that hand made sellers will move to other platforms when WE are not satisfied with their customer service. DONT SET UP A SHOP ON ETSY.
