i have discovered a new place to buy duty online: booktopia. $22.46 + $6.50 postage = $28.96, meaning u pay $4.01 over retail. if you buy more though its the same postage up to 100 books - unless im misunderstanding. it seems like a good option if u live in australia but not close to a decent bookshop - or if its incovenient to go shopping for something u might have to order & go back & collect, all the while paying for yr travel etc. if anyone tries this option, feedback on timeliness wd be great.
