I have been receiving messages at my email address from customers requesting to purchase items privately because they don't want to sign up and have an account on Etsy. I can understand this because there have been plenty of sites that I have purchased from that I don't want to register so I just go through guest checkout.
This is not a problem for me since I can process credit cards myself and it's less fees for me. I am just curious as to why Etsy wouldn't offer this, really they must know that they are losing revenue. You would think that as the greed works its way into their blood that they would try to capture every dollar that they possibly could.
