Right on. Well, one thing that's helpful to know is that it's better to hit the reply button on someone's comment. It's sends them a notification so they know you've responded. A lot of people miss that. Let's see. For books, media mail or a flat rate box are probably going to be your best options. I'd say take these up to the po when you have time and ask them to weight them and let you know the cheapest options. Also, it's a pretty good idea to add delivery confirmation to your packages. Gives your auction winners piece of mind and proves that you mailed the item in case it gets lost in the system and you have a dispute. Hopefully that'll help getcha started. Don't hesitate to message if you have questions!!
I may or may not be up when this is over. If I win please send me a list of the titles and authors when you can. Thanks! If I don't win, congrats to the winner and lister!
