At Lifehacker, we freely admit to having something of an office supplies fetish. That might well be a pre-requisite for installing the Officeworks iPhone application, which lets you browse 15,000 items from the office supplies giant. Mmm, staplers.
The app doesn't include any online shopping support, but can be used to locate the nearest store, presuming you don't just jump straight into Mobile Safari. You can build a wish list for future purchases, which is a potentially useful option -- I'll fess up to already having a "stuff I might buy in Officeworks one day" list on my BlackBerry, even though the chain doesn't offer FlyBuys any more.
