If you sell through Etsy and ship through Paypal like I do… here’s some quick links I use often. If the buyer did not pay through Paypal you can still use Paypal to ship! Use the ship now link below! I bought a food scale to use at home and it comes very handy. No dragging three kids to the post office! I do all my shipping from home. And if you use something like paypal for shipping, tracking is always included. The rates went up again! See below for current postage rates.
