Trying to find an alternative to this great price on ShoppingExpress (in case I don't grab one).

Used to use MyMemory a lot when in the UK and they were great and have also ordered a few items (though not recently to Australia). Quite a few other bargains on the site! Postage is £1.95 (~$3.50) for the first item and £1 for subsequent items. Worth a try!
