I think $42 is good price for a top range keyboard from Logitech.
Next cheapest I could find is $185.
But The Co-op will require $25 lifetime membership if you want it at this price.
This is my first post here so if anything is missing or or I did wrong, please let me know.
Thanks
Update: I don't know why some people have problem with their website is saying it is out-of-stock. But I placed an order at 9:20am AWST, and got the order confirmation straight away, so it was ok for me.
Update again: at 9:30 AWST, seems like it's another price error or got Ozbargained.
it says out of stock when added to cart
