I'll say one thing though, if you're using the e-mail facility on e-bay...it's 100% dodge, I never receive confirmations etc etc and always have to include an instruction for the sellers to contact another e-mail addy, it's that bad.
As for Australia post losing things...don't get me started on that issue. The most recent thing has been with our mail being redirected to a PO box...now anyone sending stuff to our home addy gets it returned to sender, even though it's a valid address.
I've got things being sent by friends and it's taking months for it to arrive, so I know some of you guys would be getting edgy about strangers sending stuff, but just remember Aus Post is useless at the best of times.
