shari_nat- I wasn't aiming this particularily at any one particular seller- but at the general consensus some have that shipping ASAP matters. Even it means running to the Post Office whenever anyone buys anything.
We have a Canada Post red mail box- about 50 feet from where I am typing this, So- I could simply walk accross the street, and drop everything in the box. I can even watch them scan packages, where I have preprinted the label. It's that close, and right outside my window.
We choose to go to the Post Office- that's our choice.
I amy re-think this, as dropping somethings in the box late at night, would be picked up first thing in the morning. This may actually speed up our deliver. However- I don't have those hang ups at delivery time. So, like you, when we happen to be going near a Post Office, we take the mail. At other times- it waits until it's convenient.
Not everyone is fortunate enough to be minutes away from a Post Office. Not everyone has a Post Box outside their window. Gas is a very real cost- right up there with boxes, and bubble wrap. And maybe that's a BIG thing eBay has never truly factored into their notion of what actual shipping and handling charges are.
