I'm new to selling comics and have half a dozen short boxes to start listing. For some books, I'll be selling individually. For cheaper items, I'll be making small lots.
Either way, I've gotten a bundle of Gemini II mailers. Once I have the book(s) in the mailer, especially less expensive books, what's the best way to ship? Simply put a label on the Gemini mailer? Put the mailer in an envelope? Put the mailer in a box?
For books or lots >$25, I plan to use Flat Rate (legal sized) Envelopes. Seal the Gemini, slip it into the envelope...easy.
What about the cheaper books/lots? Most people won't want to pay $9 shipping on items of that value...
Two quick caveats:
I won't use Media Mail
I'm at the Post Office nearly every day (for other sales) already, so USPS is strongly preferred
