It is so easy to use
It is so easy to use. That said, I learned by trial and error. My first Etsy sale sat in limbo for about a week before I realized I had to pay for the product first. I thought the customer paid. Mistakes like that only happen once and since then, my sales have gone smoothly. At the same time, there seems to be a rather thin profit margin. idk if that's applicable to all fulfillment centers.
