Tissues aren't a core Lifehacker topic, but saving money definitely is. So we feel obliged to note that right now on the Officeworks site, there's a carton of 24 boxes of tissues on sale for one cent. (Update: not any more, alas!)
Of course, we need to issue the usual warnings. Chances are that this is a data entry error and will be corrected as soon as Officeworks notices. Officeworks might well choose to honour orders placed before that happens, but as we've learnt with previous pricing errors, that isn't guaranteed (and being all righteous about it if that happens makes you look like a tool, frankly).
The other point is that you'll need to pay shipping for the item. Officeworks delivers free if you spend more than $55, so if you're planning to order something in that price range anyway, the free carton of tissues might be a useful bonus. You can also order items for pick-up in store for a $4.95 handling fee. That still makes the tissues pretty cheap, assuming the offer stands -- but I'll point out again that it's probably an error and anything could happen. Thanks Praveen for the spot!
UPDATE: The price has now been adjusted back to $62. We'll wait and see what happens to anyone who actually placed an order.
