If there are no shipping options, I shop around for the same product elsewhere, express post is usually only $10AUD more and will sometimes arrive 1-2 days later, usually never more than 4 days. Couriers for $30AUD will usually definitely arrive 1-2 days later. Even ordering internationally can be faster than standard post to my address these days.
So I usually bail out of a transaction if there's no shipping options, its easier to just find another source than it is to ask and arrange for shipping personally.
