Media mail can take up to 2 weeks. We did a bit of research and compared the prices and the difference wasn't enough to justify the extra long time and have to deal with the problems associated with packages taking forever to arrive. We pride ourselves on having super duper fast order fulfillment and ship times and that would go down the tube if we used media mail.
With that said, if Terrie is okay with shipping something via media mail at special request, she may be willing to work that out.
I am anticipating that the cookbook's weight will make it less expensive to just ship it in a flat rate priority envelope. Of course I will redo all my calculations when they get here, but based on the info I have, that is the best way to go.
