Emsgrammy, this is a great post.
Just a thought here, a little off topic but something to make shipping easier for you. Have you thought about getting an online USPS account??? It makes shipping soooooo much easier!!
I have an ebay business and never go to the post office and it's free to have an account. I use my Paypal shipping for ebay but my USPS for gifts, board things, etc. My carrier picks up all my things.
They won't let you ship First Class online though, (unless you ship with Paypal shipping) that's the only thing I wish they would do. Other than that it's really convenient.
