Nora, could be they match PayPal; I use PayPal always, and it is a bit lower than USPS online quotes. So I thought If I gave a shipping quote I could use the USPS rate and be safe. Fortunately, I added a bit to the quote to cover costs of shipping materials but it still "rang up" higher on the Etsy label.
The one thing I do like is that with PayPal, you can edit the shipping preference and compare what one service costs vs another, and then hit PAY.
Does Etsy work that way...am I missing something? Could be!
This was my first label with them.
