There is no need for any of this.
The buyer paid, the seller ships book.
That's it.
It's that simple.
I don’t see what the seller did wrong in his initial contact. Was he too formal? I’ve also had folks buy things whose ebay addresses that did not match their PP addresses. Maybe I’m misunderstanding things.
OP buys item.
Seller starts to process order, see addresses that don’t match (a potential red flag for getting ripped off) and asks OP to confirm his address.
OP writes aggressive, snide response without confirming address.
Seller decides, “Uh-oh. This is trouble.” and cancels order.
Like jsilverjanet, i would have probably written a second email rather than cancelling the sale, but if the seller sees different addresses, what is the big deal about confirming the correct one?
