The clearance section on repco can often be trawled for some really cheap items. For the next week there is a further 20% off. The trouble as always with the website is finding the in-stock items. I think you have to try setting different stores as your location. Even if they say there is stock it is also worth ringing the store to confirm.
I'm trying a decending price link, but not sure if it will work

Also if they advertise a product wrong and you contact them about it they just ignore emails, and the shipping store defers responsibility to the online store. And they'll just keep ignoring the issue for months until you go away.
I've stopped buying from these. They advertised a 4-pack of Energizer AA rechargables, great price for a four pack, terrible price for a 2 pack. Got a 2-pack and eternal excuses and bullshit. Glad I didn't buy more than that, or anything pricey.
