Thanks to all who responded with thoughts, ideas, and suggestions. Once I figure out what happened, I'll update this thread. Computer glitch or operator error...or standard procedure for either the bank or usps/pitney bowes. we'll see.

I do agree with you, wrk101 about using the ebay print function. I'll look into it next time.

EDIT/UPDATE: They(pitney bowes) charged it again, so they now have their money. yay. all is well.
