Ran across this while looking for mother's day presents, includes their website & their stores.
Note that their major competitor, Word Bookstore (word.com.au) is also having a 'massive' 25% off Bibles & Kid's books + 20% off Music, DVD's, Books + 1000's more discounts instore - might be worth a look but I think often more expensive to start with (and their website didn't actually show the 20% discount upon looking at prices…)
